A prospective study was conducted on 90 eyes undergoing extracapsular cataract extraction and posterior chamber IOL implantation. Postoperative IOL decentration was evaluated with respect to the loop material, either polypropylene (prolene) or polymethylmethacrylate (PMMA), and the IOL fixation technique, either in the capsular sac (in-the-bag) after capsulorhexis, or in the ciliary sulcus after “can-opener” capsulotomy. More decentration was observed with IOL having polypropylene loops than with those having PMMA loops (0.80 ± 0.735 mm versus 0.373 ± 0.299 mm). IOL implanted in the bag showed greater decentration than those implanted in the sulcus, but the difference was not significant. Our findings confirm the recommendation to use an IOL with PMMA loops when placing the implant in the capsular sac.

A total of 143 anterior chamber (AC) intra-ocular lenses (IOL) of various designs were implanted in a five-year period and followed for 18 to 76 months. The lenses were inserted as a secondary implant after extracapsular cataract extraction (ECCE) complicated by vitrectomy, or after primary intra-capsular extraction. The complications (corneal edema, uveitis/glaucoma, extrusion/imbedding, cystoid macular edema), the final visual acuity and the need for removal of the IOL were analyzed. Only small differences were found between the different lenses but some association was found between complicated surgery (ECCE + vitrectomy) and a higher rate of complication, poorer visual outcome and more frequent need for IOL removal. Cystoid macular edema was encountered only in cases with complicated ECCE. A high percentage of other ocular pathologies was found among the cases, possibly implying that diseased eyes are more prone to surgical complications. An alternative to the AC-IOL in cases with a ruptured posterior capsule is the suture-supported posterior chamber IOL, but the flexible-loop AC-IOL may not yet be obsolete.

As part of a retrospective sudy, 1056 eyes of 940 patients who had undergone extracapsular cataract surgery and posterior chamber IOL implantation were studied using statistical methods (chi-squared test). We studied the presence of fibrin reaction in three subgroups: diabetics without retinopathy (102 eyes), previously operated for primary open angle glaucoma “POAG” (78 eyes) and exfoliation syndrome without glaucoma (43 eyes). The results were compared for these three groups and for a group of normal individuals. The incidence of fibrin reaction was 13.7% in the diabetics, 44.8% in the group of previously operated POAG and 27.9% in the group of exfoliation syndrome without glaucoma. All the groups studied had this complication much more often than the controls (p < 0.0001). The incidence among previously operated eyes for POAG was higher than in diabetic eyes without retinopathy (p < 0.0005) and in exfoliation syndrome without glaucoma eyes (0.05 < p < 0.1). Fibrin reaction was more common in exfoliation syndrome without glaucoma than in diabetic eyes without retinopathy (p < 0.05).

The study of 30 patients was performed at Lahore General Hospital, and Institute Of Ophthalmology Mayo Hospital, Lahore from June 1989 to June 2003 for 14 years. Total number of eyes were 34 where 2 patients had both eyes. Age ranged from 12-65 years. Males were 11 and females were 19. all the patients had planned extracapsular cataract extraction with IOL implantation. Total follow up period ranged from 1-5 years and best corrected visual acuity in these patients after surgery was 6/12 to 6/6. Post operatively, eyes had vitreous membranes and glaucomatous reaction.

Background: An effective method for cataract surgery should be identified to combat cataract blindness. Aim: To study the surgical outcome of conventional extracapsular cataract extraction versus manual small-incision cataract surgery. Materials and methods: A randomized clinical trial was carried out including one hundred eyes (88 patients) which were divided into two groups using systematic randomization: groups of conventional extracapsular cataract extraction with posterior chamber intraocular lens (ECCE with PCIOL) implantation and manual small-incision cataract surgery (MSICS). The postoperative parameters/variables studied were the unaided and best-corrected visual acuity and astigmatism. Statistics: Epi info 2000 version statistical software was used for data analysis and calculation of relative risk, 95% CI and p value. The p value of less than 0.05 was considered as significant. Results: In the immediate postoperative period, unaided visual acuity of =/> 6/18 was achieved in 24 subjects in MSICS group versus 7 in ECCE with PCIOL group (RR=2.05, 95% CI=1.44 - 2.94, p = 0.0002), whereas the same at 6 - 8 weeks postoperatively was found in 28 and 22 subjects in those groups respectively (RR=1.27, 95% CI=0.86-1.89, p=0.23). The astigmatism of =/> 2 at 6 - 8 weeks was found in 35 and 17 subjects from the conventional and MSICS groups respectively ( R=2.28, 95% CI = 1.39-3.73, p=0.0002). Conclusion: Both MSICS and conventional ECCE with PCIOL are safe and effective techniques for treatment of cataract patients. A more rapid recovery of good vision can be achieved with MSICS than with conventional ECCE with PCIOL in the immediate postoperative period.
