The biocompatibility and fixation of a new silicone intraocular lens was evaluated in the cat eye. Following extracapsular lens extraction, 14 cats were implanted with a silicone lens (SLM 2/UV type) with polypropylene modified J loops in one eye and a poly(methyl methacrylate) (PMMA) lens (Perspex CQ) of a similar design in the fellow eye. Half the lenses were placed in the ciliary sulcus and half in the capsular bag.

Cataract surgery was performed in six eyes of four patients with typical colobomata of the iris, choroid, and retina. Contrary to previous reports of poor surgical results in these eyes, we saw no surgical or postoperative complications. Final visual acuity was excellent in four eyes.

Intraocular lenses containing an ultraviolet chromophore, representing the products of seven manufacturers, were analyzed for chemical and ultraviolet transmission characteristics and the results are reported. The clinical use of this type of intraocular lens and the absence of any long-term safety data are discussed.

Internal tubing involved in the venting and vacuum mechanism of CooperVision's models 8000-V, 7500, and 6500 units were cultured. Several species of bacteria were found including Staphylococcus epidermidis. The clinical implications of this are discussed as well as a solution to the possibility of intraoperative bacterial contamination from the reported source.

In a series of 1,000 consecutive cases of posterior chamber intraocular lens implantation, 49 patients were monocular, being irreversibly 20/200 or worse in the unoperated eye. The results of surgery on these patients are reported and it is noted that three patients required subsequent additional intraocular surgery, one of these cases related to loss of vision in the unoperated eye which affirms the bilaterality of some ocular disease. While intraocular lens implantation may be performed on monocular cases, attention should be given to the reason for visual loss in the fellow eye; moreover, both patient and surgeon should consider the risks involved.

A prospective study investigated the effect of local anesthesia, eyelid edema and superior rectus muscle injury on postoperative ptosis. Patients were randomized into four groups to study these effects. Group A received a Van Lint eyelid block and a superior rectus bridle suture.

Bimanual phacoemulsification.

Aust J Ophthalmol

February 1984

Phacoemulsification is widely used in the USA for cataract extraction. The surgeon's ability has been enhanced by improved instrumentation and evolution of techniques which make the surgery less challenging. Such a technique is bimanual phacoemulsification, which is described in this paper.

We analyzed two consecutive series of cataract extractions in patients with moderate to severe myopia for the incidence of postoperative retinal detachment. One series consisted of 122 intracapsular cataract extractions without surgical loss of vitreous and the other series consisted of 151 extracapsular (phacoemulsification and planned extracapsular) cataract extractions without loss of vitreous and with intact posterior capsules. All patients were 40 years of age or older and all were followed up for one to four years.

For 32 eyes tested for glare disability after undergoing extracapsular cataract extraction with implantation of posterior chamber intraocular lenses, the mean contrast threshold in the presence of the glare source was 23% for undilated pupils and 31% with dilation. A regression analysis of glare scores as a function of the amount of posterior capsule opacification showed a significant (P less than .00001) association between the two.

A study of 1796 consecutive cataract patients in a posterior chamber intraocular lens implant (IOL) series revealed 373 patients (20.8%) who had bilateral IOLs. Visual acuity was 20/40 or better in 87% of first eyes operated and 90% in second eyes.

A new posterior chamber intraocular lens with an ovoid optic is described. The horizontal diameter is 5 mm and the vertical 6 mm, permitting insertion through an incision fractionally greater than 5 mm. The results of the first 100 cases are presented; 97% of patients attained a visual acuity of 20/40 or better.

A retrospective study of 450 consecutive intracapsular cataract extractions with a Binkhorst lens implant, and 450 consecutive extracapsular cataract extractions with a posterior chamber lens implant, was performed. All patients were examined between 34 and 40 months postoperatively, except for those patients who died before this time, those lost to followup, or those who were otherwise unavailable during this time. The results suggest that the extracapsular series had a more favorable outcome than the intracapsular series, especially with regard to final visual acuity and the incidence of clinical cystoid macular edema.

A prospective cystoid macular edema study of aphakic and pseudophakic patients showed that extracapsular cataract surgery has a lower rate than intracapsular surgery when the surgery is uncomplicated. There was no difference in the rates with intracapsular surgery with and without an intraocular lens. A complicated extracapsular with an intraocular lens has a higher rate than when the surgery is uncomplicated.

A series of 300 consecutive extracapsular cataract extractions with a Shearing posterior chamber lens implant (plus 13 with a surgical complication necessitating another kind of lens implant or no implant) was evaluated 34 to 40 months after surgery, except for those who died before this time (21 patients) and those lost to follow-up (15 patients). Ninety-one percent of the 264 patients who were examined achieved 20/40 or better visual acuity. Ninety-one percent of the 300 patients (those examined plus those who died and those lost to follow-up according to their last recorded examination) achieved 20/40 or better visual acuity.

A large series of patients with intraocular lens implants had an overall 0.98% incidence of retinal detachment (eight detachments in 819 eyes). Within this group, patients with axial lengths of more than 25 mm had a statistically significantly higher incidence of retinal detachment (P = .

We performed a prospective fluorescein angiographic study on 66 patients who had undergone extracapsular cataract extractions with implantation of a Shearing posterior chamber intraocular lens. A primary posterior capsulotomy was performed in every case. The eyes were studied 11 to 23 months postoperatively.
