New Diagnosis

We report the self-limited nature of corneal opacification after accidental injection of Healon5 into the corneal stroma. A 52-year-old male with a new diagnosis of severe stage, primary open-angle glaucoma underwent successful trabeculectomy OS, which was complicated by ocular hypotony and shallow anterior chamber (AC) on postoperative day 1. Healon5, a hyaluronic acid-containing viscoelastic device, was accidentally introduced into the corneal stroma during attempted injection into the AC. The cornea hydrodissected and opacified, leading to precipitous loss of best-corrected visual acuity (BCVA). The corneal opacification spontaneously resolved over a 7-month period without specific intervention. During this period, the patient also underwent cataract extraction with posterior chamber intraocular lens placement and YAG capsulotomy, after which his BCVA returned to approximately baseline. Though intrastromal injection of sodium hyaluronate-containing material has been reported elsewhere, this complication with Healon5 use specifically has yet to be described in the literature and may occur in any procedure involving Healon5 in the AC. This case report is important, since the precipitous loss of BCVA can be alarming to the ophthalmologist and the patient. The affected patient may be counseled that the opacification should improve with time.

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.

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).
