cornea may severely impair adhesive and migratory properties of corneal epithelial cells. Such alteration in the corneal cell BM adhesion may be the mechanism underlying clinically observed abnormalities in epithelial barrier function, adhesion, epithelial integrity and wound healing 13 . Raised IOP also contributes to this increase in the number of post-operative corneal edema. Bleeding in AC had occurred in 1% post operatively and 1% intra operatively. Bleeding is a common complication arising in diabetics due to the nature of the diabetic tissue. The rate of post operative inflammation was 10% in this study, when compared to non-diabetics 1.8%. Retained lens material in 3% especially the superior cortical material was due to inadequate mydriasis. One of the patient, a fifty year old female developed expulsive supra choroidal haemorrhage on the second post operative day. She was diagnosed to have phacolytic glaucoma with hypertension. Evisceration was done to remove the prolapsed uveal tissue and hence prevent sympathetic ophthalmitis.

and group B respectively. The inclusion criteria for selection was- all cases of senile cataract with different grades of nuclear sclerosis including brown cataracts and hypermature cataracts, clear corneas and no or minimal preoperative astigmatism (0.25D—0.5D). All patients were between the age group of 50-85 yrs. Exclusion criterion was- glaucomatous eyes, corneal dystrophies, posterior segment pathology and patients with previous history of trauma or surgery. Patients who were lost to follow up and cases in which phaco was converted to manual small incision cataract surgery (SICS) due to extension of capsulorrhexis were also not included in the present study. All the patients underwent detailed ophthalmological examination which included BCVA, slit lamp examination, ophthalmoscopy, tonometry, keratometry and biometry (USG A scan). All the patients were operated using superior clear corneal incision by the same surgeon to avoid inter surgeon variation on Alcon Laureatte phaco machine. The incision size of 2.8mm was enlarged to 6mm at the end of surgery to implant a rigid (PMMA) 6mm optic IOL in group A and 3.2mm to 3.5mm in group B to implant a foldable IOL. (Alcon multipiece) The final outcome measures of the study were uncorrected visual acuity (UCVA) at day one after surgery, best corrected visual acuity(BCVA) and surgical induced astigmatism(SIA) at 6 weeks, intaoperative and postoperative complications. Though posterior capsular opacification and cystoid macular edema are important postoperative parameters, they were not compared, as complete record for all the cases was not available.

A comparison of patient pain and visual outcome using topical anesthesia versus regional anesthesia during cataract surgery

A comparison of patient pain and visual outcome using topical anesthesia versus regional anesthesia during cataract surgery

To the best of our knowledge, this is the first study to compare the efficacy of three types of anesthesia (topical, sub-Tenon, and intracameral) during cataract surgery. In the present study, all types of anesthesia provided good patient comfort, as none of the patients required additional anesthesia during surgery. Additionally, no complications caused by anesthesia were noted in any of the patients. There were no differences in visual outcome and corneal endothelial cell loss between the groups. The mean percentage of corneal endothelial loss in all patients was 8.0%, and this result is almost similar to previous studies. 3,18 The duration of surgery was shortest in

Cataract surgery by appointment – a pilot study

Cataract surgery by appointment – a pilot study

Background: "Cataract Surgery by Appointment" is a new method of delivery of cataract surgery that reduces the time a patient spends in hospital by their direct arrival at the operating theatre, having self-prepared for surgery, thus avoiding admission to the ward or time spent in the Day Case Unit. The patient can stay as little as 20 minutes from their arrival to going home. We describe the process in detail, and seek to evaluate the visual outcome, safety and patient satisfaction of same. Methods: Visual outcome and safety data were obtained from patients' medical records, prospectively. Patients were also surveyed by a questionnaire to determine their satisfaction with the service and viability as a prospect for providing a more efficient cataract surgery service. Results: In 2002, fifty-one eyes of 39 consecutive patients underwent "Cataract Surgery by Appointment". There were 16 male and 23 female. The pre-operative best-corrected visual acuity was 6/9 or better in 17 (33%) eyes. The post-operative best-corrected visual acuity was 6/9 or better in 44 (86%) eyes. There were no per-operative complications. Post-operative complications occurred in 3 (6%) eyes. The average number of days from surgery to final discharge was 14.5 days. Twenty-eight (72%) completed questionnaires were returned. The results show that the majority of patients were satisfied with their overall experience of this mode of delivery for cataract surgery. Conclusion: "Cataract Surgery by Appointment" performed under local anaesthesia by a skilled ophthalmic surgeon appears to be safe and effective for highly selected cases. This method of delivery gave a high level of patient satisfaction, and is the ultimate form of day case cataract surgery. The method may gain widespread use should per-operative intracameral pupil dilatation prove to be effective and acceptable. Attention should be paid to risk-stratification, so complex cases are allocated more time on the operating list.

Risk factors that associated with visual outcome of community based cataract surgery

Risk factors that associated with visual outcome of community based cataract surgery

The weakness of this retrospective study that the data was incomplete including the age of the patient (58.24%) due to lack of postoperative recording; and post-operative visual acuity (14.2%) because patient did not attend on the first post-operative day. Besides, some patient’s pre- operative visual acuity were not measured by Snellen chart, systemic comorbidities and ocular pathologies were not analyzed, the post-operative visual acuity on the first day was not examined with the best correction, and the follow-up period was limited to the first post- operative day so the patient's visual acuity progress and post-operative complications could not be followed.

A study of visual outcome of cataract surgery in children

A study of visual outcome of cataract surgery in children

Complication may include choroidal detachment or wound leak. Satisfactory visual acuity following cataract surgery was associated with eyes having open globe injuries and managed using a primary posterior capsulectomy and vitrectomy as the primary procedure (Parikshit Gogate et al., 2012). Patients with traumatic cataract can have an optional or best possible visual outcome depending upon management and complications (Srivastava et al., 2014). Lesueur L said that regained binocular vision and absence of amblyopia depend on the quality of previous visual experience and absence of post-operative strabismus. Implantation appears beneficial for final visual results (Lesueur et al., 1995). Staffieri SE etal said in a paediatric population, cataract formation as a result of trauma requiring lensectomy is not uncommon. Males are more likely to suffer from such injury. A variety of sharp and blunt objects are the primary mechanism by which the injury is sustained with variable visual outcomes (Staffieri et al., 2010).

Factors predicting the visual outcome in Patients with acute post operative Endophthalmitis following cataract Surgery, in a Tertiary Eyecare Centre in South India

Factors predicting the visual outcome in Patients with acute post operative Endophthalmitis following cataract Surgery, in a Tertiary Eyecare Centre in South India

Study by Aurelie et al has shown that absence of complications during cataract surgery is an independent factor for good visual acuity. [17] Lalitha P et al has reported that Intra operative PCR was a significant risk factor for endophthalmitis independent of age, type of surgery, and gender. [3]. The hypothesis as stated in literatures is that bacterial elimination is less efficient from vitreous cavity than from anterior chamber.PCR may lead to prolonged duration of surgery with more instrumentation which are additional factors contributing to infection. Menikoff et al [24] has reported 13.7 times higher risk of developing endophthalmitis in patients with PCR.

Factors affecting visual outcome and progression of diabetic retinopathy after cataract surgery in type II diabetic patients

Factors affecting visual outcome and progression of diabetic retinopathy after cataract surgery in type II diabetic patients

Aiello et al found that, following ICCE, patients with or without background retinopathy were at particularly high risk of developing vitreous haemorrhage, presumably reflecting progression of the disease to PDR. Alparl and Pollock et al observed deterioration of diabetic retinopathy in some diabetic patients following either ICCE or ECCE, with the least progression occurring in patients who underwent ECCE with IOL implantation in the capsular bag. Although clinical evidence suggests that ICCE may have a more deleterious effect than ECCE on the postoperative course of diabetic retinopathy, the precise role of the posterior lens capsule in reducing vascular complications after cataract surgery in diabetic patients requires further investigation.

THE CASE STUDY OF CATARACT SURGERY

THE CASE STUDY OF CATARACT SURGERY

• Swelling or edema of the focal piece of the retina, called macula, bringing about macular edema, can happen a couple of days or weeks after surgery. Most such cases can be effectively treated. Precaution utilization of nonsteroidal mitigating drugs has been accounted for to decrease the danger of macular edema to some extent • Other possible complications include: Swelling or edema of the cornea, in some cases related with overcast vision, which might be transient or lasting (pseudophakic bullous keratopathy). Uprooting or separation of the intraocular focal point embed may once in a while happen. Spontaneous high refractive mistake (either nearsighted or hypermetropic) may happen because of blunder in the ultrasonic ecobiometry (measure of the length and the required intra-visual focal point control). Cyanopsia, in which the patient sees everything tinted with blue, frequently happens for a couple of days, weeks or months after expulsion of a waterfall. Floaters ordinarily show up after surgery.

Visual outcomes, efficacy, and surgical complications associated with intracameral phenylephrine 1.0%/ketorolac 0.3% administered during cataract surgery

Visual outcomes, efficacy, and surgical complications associated with intracameral phenylephrine 1.0%/ketorolac 0.3% administered during cataract surgery

the FDA trial received standardized topical preoperative mydriatics (phenylephrine and tropicamide) and anesthetics (lidocaine or tetracaine), they did not receive intracameral Epi or a topical NSAID. The purpose of this study was to evaluate, in a real-world setting, the incidence of periopera- tive complications, length of surgery (LOS), and use of pupil dilation devices in a broad patient population, including those with comorbid conditions that would make surgery more dif- ficult, such as IFIS, pseudoexfoliation, and otherwise poorly dilating pupils. To reflect common clinical practice, the P/K treatment group was compared to a control group receiving intracameral Epi, and all patients in the study received standard preoperative topical NSAIDs.

Visual outcome of cataract surgery at Gondar University Hospital Tertiary Eye Care and Training Center, North West Ethiopia

Visual outcome of cataract surgery at Gondar University Hospital Tertiary Eye Care and Training Center, North West Ethiopia

Data were collected by trained graduate class optometry students using a well-organized data extraction format that consisted of sociodemographic data, clinical characteristics of the study subjects, pre- and postoperative visual acuity through document review. The preoperative evaluations including anterior segment slit lamp examination, dilated fundus examination, and biometry (keratometry and A-scan) were conducted by ophthalmology residents. The surgical procedure for all eligible study participants was done by senior ophthalmologists. The level of both pre- and postopera- tive visual acuity was categorized using WHO classification as good visual acuity (6/6–6/18), borderline visual acuity ( < 6/18–6/60), and poor visual acuity (< 6/60). It was measured using 6 meter Snellen’s vision chart. For those who could not read letters at 6 meter, their vision was measured by moving the chart as close as possible. Finally, for those who could not see any letter, counting finger and hand motion were used to measure their vision. The postoperative evaluations were performed by the surgeon who operated the case.

Longitudinal study on visual outcome and spectacle use after intracapsular cataract extraction in Northern India

Longitudinal study on visual outcome and spectacle use after intracapsular cataract extraction in Northern India

Nevertheless, our study suggests that the distribution of standard +10D spherical spectacles is inadequate, in terms of provision of best vision to the acceptors of intracapsu- lar cataract surgery. The wide range of powers accepted by the participants necessitates proper refraction at six weeks post-operatively and provision of good quality spectacles of correct power. However, this would require another visit by the patient to the campsite for receiving the best- corrected aphakic spectacles and will also incur additional costs. It is likely that a patient who has come twice before, once for the surgery and the second time for removal of sutures will be willing to come again if he knows that the new pair of spectacles will provide him with better vision than the standard +10D spherical spectacles which are dis- pensed at the time of suture removal, 4–6 weeks operatively.

United Kingdom National Ophthalmology Database Study of Vitreoretinal Surgery: Report 1; Case mix, complications, and cataract

United Kingdom National Ophthalmology Database Study of Vitreoretinal Surgery: Report 1; Case mix, complications, and cataract

undertaken on 9619 eyes, of 8741 patients, over 8 years, from 27 sites. Surgical data included the indication for surgery, all procedure elements, and whether or not an intraoperative complication occurred. Post- vitrectomy cataract data were also analysed. The main outcome measures were a description of the indications for surgery, intraoperative PPV complication rate, and percentage of eyes undergoing post- vitrectomy cataract surgery (PVCS). Results The most common indications for VR intervention were retinal breaks and rhegmatogenous retinal detachment (48.5%), macular hole (9.8%), epiretinal membrane (9.6%), and diabetic eye disease (7.3%). Overall, 7.8% of PPVs had at least one intraoperative complication—the most common were iatrogenic retinal breaks (3.2%), and lens touch (1.2–1.6% of phakic eyes). PVCS occurred in 50.2, 68.7, and 74.0% of eyes at 1, 2, and 3 years, respectively.

Visual Outcome and surgically induced astigmatism in manual small incision cataract surgery versus phacoemulsification with rigid 5.25mm PMMA IOLs

Visual Outcome and surgically induced astigmatism in manual small incision cataract surgery versus phacoemulsification with rigid 5.25mm PMMA IOLs

Success of cataract surgery is determined by quicker visual and functional recovery and least surgically induced astigmatism. Factors affecting surgically induced astigmatism are the artitecture and location of incision, the surgical skills, accuracy of biometry and to a greater extent on the pre existing astigmatism. There were a total of 80 patients in our study. in group 1, 40 patients were included who underwent manual SICS with rigid 5.25mm PCIOLs. Group 2 also comprised of 40 patients who had undergone phacoemulsification with rigid 5.25mm PMMA PCIOLs implantation. the comparison was made in terms of surgically induced astigmatism and visual outcome.

Prevalence and visual outcomes of cataract surgery and cataract surgical coverage in Sri Lanka: findings from the National Blindness and Visual Impairment Survey

Prevalence and visual outcomes of cataract surgery and cataract surgical coverage in Sri Lanka: findings from the National Blindness and Visual Impairment Survey

Visual outcomes after cataract surgery were better than in many other LMIC (Table 5) [19-25,34-39], with poor outcomes only slightly higher than the WHO recom- mended levels of <5% (12.1% presenting VA; 8.8% best correction VA). Visual outcomes h ave improved significantly in Sri Lanka due to the near universal use of IOLs, which have recently been provided free by the Ministry of Health. Even though the survey could not assess cause of poor outcome for about 78% of the eyes with the poor outcome, it suggests that some poor visual outcomes were due to recognized complications, such as posterior capsule opacification, which could be addressed by counselling patients to return for follow up should they notice a decline in VA. The relatively high proportion of poor outcomes in the youngest age group (26.3%), where CSC was 100%, may be because surgery was undertaken following trauma or complicated secondary cataracts.

Chronological developmental study in cataract surgery

Chronological developmental study in cataract surgery

The accomplishment of technology has been one of the major features of the 20th century. Ocular micro-surgery has for decades been on the crest of this wave (figure 4). Suture less manual cataract surgery (known as small incision cataract surgery) is increasingly used as a substitute of phacoemulsification. In this technique a self sealing incision of about 6.0 mm is made outside the limbus. A tear is made in the anterior capsule, and the firmer portion of the cataract (nucleus) is expressed out of the eye through this incision. When done properly this technique can be performed rapidly, and suturing the incision is seldom needed, making it appropriate for high however with SICS the results are not as edictable as with phacoemulsification, it gives an acceptable outcome and has proved to be economically viable in the developing world. Extracapsular cataract extraction with good surgical technique is important in high volume centres ue is affordable, 16 and in such centres this technique involves fewer postoperative complications.17 18. In developing countries most surgery involves a rigid intraocular lens rather than a foldable one because of the latter’s substantially greater cost.
