PURPOSE To study in situ the intraocular position of the Artisan iris-claw intraocular lens (IOL) (model 203) (Ophtec) in phakic hyperopic eyes using ultrasound biomicroscopy (UBM). METHODS Echograms of the anterior chamber were taken preoperatively and 24 to 317 days postoperatively in 4 eyes implanted with the Artisan IOL (power +4.0 to +6.0 diopters). The preoperative anterior chamber dept...

Forty patients subjected to extracapsular cataract extraction with posterior chamber intraocular lens implantation in whom a sphincterotomy was required are reported on. This method was used to counter the problems created by a small pupil during surgery. The technique is described and results evaluated.

Twenty-two patients with Fuch's heterochromic cyclitis had a posterior chamber intraocular lens implanted after extracapsular cataract extraction. After a mean follow-up period of 2.5 years (range, 6 to 70 months) half the patients had a visual acuity of 1.0 or more. The results compare favourably with those in the general population.

Aim: To study the analgesic effect, subjective visual experience, and visual outcome of phacoemulsification and posterior chamber intraocular lens implantation using topical anesthesia without systemic sedation for uncomplicated cataract. Patients and methods: Eighty one eyes of 81 consecutive patients with uncomplicated cataract undergoing phacoemulsification and posterior chamber intraocular ...
