Introduction: Posterior capsular opacification is caused by migration and proliferation of cuboidal epithelium from remnant of anterior capsule and equatorial part of the lens capsule. Posterior capsular opacification also called after cataract is a nagging post surgical complication following phacoemulsification or non phaco cataract surgery (small incision cataract surgery or conventional cataract surgery) ECCE with posterior chamber intraocular lens implantation. Posterior capsular opacification is actually misnomer. Though there are many factors suggested to reduced posterior capsular opacification. The incidence of PCO still exists considerably. Aims and Objective are to find out the visual improvement after Nd yag laser posterior capsulotomy. Materials and Methods: The prospective study was conducted in the department of ophthalmology of Ad-din Women Medical College Hospital, Dhaka, Bangladesh from June 2014 to June 2018. 175 patients of 189 eyes with significant PCO. Before laser capsulotomy all patients were assess by routine slit lamp examination, IOP measurement and posterior segment examination done for every patient for exclusion of Gross posterior segment pathology. Results: The study had female preponderance (58.86%). Most of the patients 165 were 40 to 80 years old (87.31%). The patients had pre laser visual acuity 6/9 to 6/18 (31.75%) 6/24 to <6/60 (68.25%). After laser capsulotomy functional visual acuity upto 6/8 were 169 (89.42%) and 6/24 to <6/60 were 20 (10.58%). The mean pre and post laser capsulotomy visual functional score were 54.45±36.44 and 94.16±50.36 respectively. Conclusion: Nd YAG laser capsulotomy is safe, non-invasive and effective procedure.

Objectives: To evaluate the management and visual outcome of cataract surgery in children. Study design: Descriptive. Material and Methods: This study included one hundred pediatric patients having cataracts over a periodof two year, from Is' January 2005 to 31 st December 2006, at the Department of Ophthalmology, SaiduTeaching Hospital, Saidu Sharif, Swat. Results: Age range was fourteen years and below. Sixty five (65%) patients were males and thirty five (35%) females. Sixty three (63%) patients had congenital or developmental cataracts and thirty seven (37%) had traumatic cataracts. Extracapsular cataract extraction (aspiration) was performed on 150 eyes. Postoperative visual acuity was recordable in 112 eyes. Acorrected visual acuity of 6/18 or better was obtained in50 (44.64%) eyes. Forty one (36.6%) eyes obtained visual acuity of 6/24 to 6/60, while in 21 (18.75%) eyesthe visual acuity remained below 6/60. The most common postoperative complication was development ofthick posterior capsule, which occurred in 51 (34%) eyes and vitreous loss in 10 (6.6%) eyes. Pupil blockglaucoma developed in 4 (2.66%) eyes. No case developed endophthalmitis. Posterior chamber IOL wasimplanted in 9 (6%) eyes. Conclusions: Management of cataracts in children is still a problem and delayed presentation leads to poorvisual outcome. The public should be educated to seek early treatment for childhood cataracts. Paramedicsand doctors should be made aware of the problem and its management. Management of unilateral cataractsis still a difficult problem. Therefore search should continue for better surgical approach and better methodsof correction of aphakia so as to achieve better visual outcome. Key words: Childhood Cataracts, Congenital Cataracts and Traumatic Cataracts.

Background: Posterior capsular opacification (PCO) is the most frequent complication of cataract surgery. The objective of this study was to determine the frequency of acute rise of intraocular pressure (IOP) following Neodymium-Yttrium Aluminum Garnet (Nd:Yag) laser posterior capsulotomy. Materials & Methods: This cross-sectional study was conducted in the Department of Ophthalmology, HMC, Peshawar, Pakistan, from July-December 2016. Sample size was 325 selected by consecutive sampling technique. Inclusion criteria were all patients having significant PCO after uneventful cataract surgery with intra ocular lens implant. Demographic variables were sex, age groups and age in years. Research variable was presence of acute rise of IOP following Yag laser capsulotomy. Pre-laser assessment included slit lamp examination and recording of IOP with Goldmann applanation tonometer by a single ophthalmologist. IOP was measured 3 hours after Nd: Yag laser capsulotomy. Rise in IOP was labeled when IOP was ≥5 mmhg from baseline. Mean ±SD was used to express quantitative variables like age. Categorical variables were analyzed as frequency and percentage. Goodness-of-fit was applied to compare the frequency of acute rise in IOP between sample and population. SPSS-20 was used for data entry and its analysis. Results: Out of 325 patients, 170(52.3%) were men and 155(47.7%) were women. The mean age of the sample was 44.92 ±23.843 years. A total of 107(32.9%) patients were 20-39 years old whereas 218(67.1%) were 40-70 years. IOP was raised in 61 (18.8%) patients while in 264(81.2%) patients it was not raised. The frequency of acute rise in IOP after Yag laser capsulotomy was significantly different in sample compared to population. Conclusion: Men were more than women, especially of old age. The frequency of acute rise in IOP after Yag laser capsulotomy was significantly different in sample compared to population.

To study "small incision cataract surgery (SICS)" for the rehabilitation of cataract visually impaired and blind patients, a retrospective study of 100 cases of cataract patients with small incision cataract surgery (SICS) with posterior chamber intraocular lens (PCIOL) implantation were done at Rajshahi Medical College Hospital. All cases were selected having corrected visual acuity less than 6/60 who were admitted at the Department of Ophthalmology for cataract surgery from March, 2006 to February, 2008. Age group of the patient range from 40 to 85 years. Age related senile cataract were selected any complicated cataract was excluded from the study. All these patients underwent SICS with 5.5 mm optic polymethylmethacrylate (PMMA) non-foldable posterior chamber intraocular lens (PCIOL) were implanted by irrigation vectis. Intra operative complication were present in 8% cases among them 3 cases (3%) required to conversion to Conventional Extracapsular Cataract Extraction (ECCE). 2 cases (2%) had small posterior capsular rent (PCR), 1 case (1%) irido dialysis & 2 cases (2%) hyphaema occurred. Postoperative complications were found in 38 cases (38%) among them transient corneal oedema occurred in 18 cases (18%) iritis occurred in 13 cases (13%), decentering of intraocular lens (IOL) occurred in 2 cases, corrected visual acuity after 6 weeks of operation were 6/12 or better in 97 cases (97% cases achieved functional vision). Induced astigmatism ± 0.50 D to ± 1.00 D occurred in 94 cases (94%) and ± 1.500 to 2.50D in 6 cases (6%). So, SICS may be the choice of surgery in respect of visual outcome with the limited facilities and surgeons. DOI: 10.3329/taj.v22i1.5037 TAJ 2009; 22(1): 132-135

Objective To asses the results are reducing and maintaining intraocular pressure of a patient having cataract with glaucoma, Performing Trabeculectomy (Filtration Surgery) and small incision cataract surgery (SICS) by the same wound & same sitting. Method and Materials This study was done at Rajshahi Medical College Hospital from July 2006 to June 2008. Forty (40) patients of age ranging from 45 to 65 years were selected randomly having cataract with glaucoma. Intraocular pressures (IOP) were 14mmHg to 17 mmHg preoperatively with anti-glaucoma medication. Visual acuity of all patients was perception of light to counting finger (CF) half meter to one meter. Thirty eight (38) patients (95%) had open angle glaucoma and two patients had chronic angle closure glaucoma. Informed consent was taken from all the patients. Trabeculectomy were done in the SICS wound. Side ports were made in every case. Delivery of nucleus, washing of cortical matter and introduction of PCIOL all are done under local anesthesia. Results :The patients were followed up 2 weeks, 4 weeks, 4 months and 6 months interval. All patients had IOP within normal limit (14-17mmHg) with medication before surgery cataract of all patients were total, fundus were invisible due to cataract. In the first post operative day (1st OPD) visual Acuity of thirty eight (38) patients (95%) were 6/24 to 6/18 and with pinhole 6/12, except 2 (two) patients (5%) among them 1 (one) (2.5%) having hyphaema. Hyphaema were relieved after 3 days by using Tab. Anaroxyl 3 times daily for 2 days and vitamin ‘C’ (250mg) daily for 15 days. After 6 weeks all patients had IOP 11mmHg to 14 mmHg without antiglaucoma medication and 39 (thirty nine) patients (95%) had achieved corrected vision 6/12 to 6/6. Except, 1 (one) (2.5%) had vision lowering counting finger 5 meter due to end stage glaucoma, who had cup disc ratio (C:D.9) 5 (five) patients (12.5%) developed polycystic bleb and rest diffuse functional bleb. Cup disc ration (C:D) of 39 (95%) was 0.4 to 0.8. no wound gap with iris proplase, thin bleb or fibrosed bleb with engorged overlying vessels were reported in any case. TAJ 2010; 23(1): 15-17

Objectives: To investigate the clinical characteristics of cataract patients with small pupils and to evaluate the result of cataract surgery on the eye have small pupils by phacotechnique. Subjects and methods: Descriptive study, prospective, uncontrolled interventions. Sample selection. The sample size of 70 patients with 70 eyes of cataracts with small pupils was treated by phaco technique and intraocular lens implant within posterior chamber. Follow up to 3 months. Results: 70 eyes, the percentage of men and women was not different from 54.2% (38 male) compared to 45.8% (32 female). The mean age was 80 ± 8.74, from 58 to 99 years. The disease was mainly found in the age group over 70 years old with over 80% (51.5%). Visual acuity before surgery was very poor under 3m CF (count finger) for 68.6% (48/70). Visual acuity over 1/10 was only a small amount with 2.8% (2 eyes). Pseudoexfoliation was the most common reason complications of mydriasis with 32/70 eyes (45.7%) and 22/70 eyes (31.4%) for age. The preoperative pupilarysizewas mostly small with 63/70 eyes (90.0%), non-dilated pupils (7/70 eyes) (10.0%). Average pupil size was 3.34 mm (2 - 4mm). Iris condition: iris atrophy 20/10 eyes (28.6%), iris synechiae 11/10 (15.7%), irregular iris muscle with 51, 4% and good iris muscle accounted for 48.6%. Grade of cataract: Grade III: 31/70 eyes (44.3%), Grade IV: 32/70 eyes (45.7%), Grade II: 5/70 eyes (7.1%) and V:2/70 eyes (2.9%). Pupil expander technique: OVD injection with 42/70 eyes (60%), using iris hook with 23/70 eyes (32.9%). Pupillary size before and after intervention has changed from 3.7mm to 4.48mm. Conclusions: Iris expander techniques have been shown to have good dilated pupils: 60.0% OVD injection, iris hook was 32.9%, other methods 7.1% One-week visibility of good visual acuity was higher than that of postoperative one day (12.2%) and increased at 1 month and 3 months (20.0%). Very good visual acuity was not available and low vision group was 1.4% after 3 months. Key words: cataract surgery; phacoemusification, small pupil

Purpose. To assess safety and efficacy of temporal manual small incision cataract surgery (SICS) in context to visual outcome, astigmatism, and complications. Methods. This involved sclerocorneal tunnel, capsulotomy and hydrodissection. The incision was made with number 11 disposable surgical blade (costing Indian Rs. 2.50, $0.05). Nucleus extraction was done by phaco-sandwich method with the help of vectis and dialer. Posterior chamber intraocular lens implantation was done according to biometric findings. A record of intraoperative and postoperative complications was made. The final postoperative assessment of astigmatism was done with spectacle correction on the 45th day as per the refraction findings. Results. Two thousand eyes were operated by temporal, manual small incision sutureless technique. Uncorrected visual acuity was ≥6/18 in 1636 (81.7%) patients on the first postoperative day, in 1652 (82.6%) patients at 2 weeks, and in 1732 (88.6%) patients at 6 weeks. Best-corrected visual acuity (BCVA) ≥6/18 was achieved in 1868 (93.4%) patients at 6 weeks, with 46 (2.3%) having BCVA <6/60, 24 (1.2%) of whom had preexisting retinal pathology. At 6 weeks, 1876 (93.8%) eyes had with-the-rule and 134 (6.2%) against-the-rule astigmatism (mean 0.7±1.25 D). Iris prolapse was noted in 3 (0.15%), wound leak in 3 (0.15%), and transient corneal edema in 136 (6.8%) eyes. Average surgery time was 6 minutes. Conclusions. Temporal SICS with number 11 disposable surgical blade and nucleus delivery by phaco-sandwich method gave excellent outcome with minimal astigmatism and low complication rate at economic cost.

Introduction: Cataract is most common cause of curable blindness worldwide and cataract surgery is most common procedure performed in ophthalmology. Posterior capsular opacification (PCO) is most common complication after cataract surgery which is usually treated with Neodymium-doped: Yttrium Garnet (Nd:YAG) laser posterior capsulotomy or occasionally with a surgical capsulotomy. The incidence and severity of PCO correlates to the type of surgical technique, IOL optic edge designs and IOL materials. Material and Methods: 70 eyes of 64 patients operated for age related cataract were studied in this prospective interventional study. Phacoemulsification was done in 35 eyes and SICS in 35 eyes with hydrophobic single piece biconvex foldable intraocular lens. Patients were followed up at 1, 3, 6, 9 and 12 months for the development of PCO. Clinically significant PCO (loss of 2 or more lines of Snellen’s visual acuity chart) was treated with Nd:YAG laser capsulotomy. Results: The overall incidence of PCO was 22.85%. Amongst the patients who developed PCO, SICS and phacoemulsification was performed in 62.5% and 37.5% patients respectively. Result was statistically significant with p value <0.05 using z test. On first postoperative day, patients operated with phacoemulsification had better visual acuity than SICS. Conclusion: Phacoemulsification can provide early and better visual outcome than SICS and has lower incidence of PCO formation which may be due to difference in irrigation and aspiration and less disruption of blood aqueous barrier than SICS. PCO can be reduced by atraumatic surgery and thorough cortical clean up and capsular polishing.

Background:The purpose of the study was to identify macular edema after cataract surgery in eyes with and without pseudoexfoliation syndrome. The study was a post-hoc analysis of a randomized, double-blind, prospective single-center study. Patients were enrolled between January 2016 and October 2016 as per the national guidelines for the management of cataract in the Department of Ophthalmology, Kymenlaakso Central Hospital, Kotka, Finland.Methods:One hundred and fifty-six eyes of 149 patients undergoing routine cataract surgery. Postoperatively anti-inflammatory medication was either dexamethasone (N = 78) or diclofenac (N = 78). Spectral domain optical coherence tomography imaging and laser flare meter measurement of the anterior chamber were conducted before surgery and at the control visit 28 days postoperatively.Results:Baseline variables were comparable between eyes with pseudoexfoliation syndrome (N = 32) and those without (N = 124), except for intraocular pressure ( P = 0.002) and glaucoma medication ( P < 0.001). In patients having pseudoexfoliation syndrome, central retinal thickness increase (mean ± standard error of the mean) was 63.3 ± 35.5 μm for dexamethasone and 17.6 ± 5.8 μm for diclofenac, compared to 28.9 ± 8.0 μm ( P = NS) and 6.9 ± 1.3 μm ( P = 0.014) in eyes without pseudoexfoliation syndrome, respectively. Aqueous flare at 28 days was 25.8 ± 5.4 pu/ms for patients with pseudoexfoliation syndrome and 18.3 ± 1.8 pu/ms for those without ( P = 0.030). Best corrected visual acuity gain and best corrected visual acuity at 28 days were less in patients having pseudoexfoliation syndrome compared to those without (0.39 ± 0.07 vs 0.59 ± 0.03 decimals, P = 0.007; and 0.77 ± 0.06 vs 0.92 ± 0.03 decimals, P = 0.008, respectively).Conclusion:Eyes with pseudoexfoliation syndrome may be predisposed to an increased aqueous flare and macular edema after cataract surgery. This study outlines the need to determine the optimal anti-inflammatory medication after cataract surgery in patients with pseudoexfoliation syndrome.
