Cataract Extraction without Iridectomy.

Bilateral cataract: extraction in classic haemophilia with retrobulbar anaesthesia and peripheral iridectomy.

A 47-year-old factor VIII deficient haemophiliac successfully underwent bilateral cataract extraction. The use of cryoprecipitates to achieve haemostasis permitted retrobulbar anaesthesia and a peripheral iridectomy without complication. We consider that the use of cryoprecipitated factor VIII concentrate allows safe elective ocular surgery in patients with classic haemophilia.

Ciliary block (malignant) glaucoma after cataract extraction with lens implant treated with YAG laser capsulotomy and anterior hyaloidotomy.

An 84-year-old woman developed high intraocular pressure with a shallow anterior chamber 2 months after an extracapsular cataract extraction with posterior chamber lens implant. The condition did not respond to peripheral iridectomy and removal of the implant but was treated successfully with YAG laser capsulotomy and anterior hyaloidotomy.

Miotics or mydriatics for atony of the ciliary muscle with delayed re-formation of anterior chamber after cataract extraction with complete iridectomy.

Conjunctival Bridge in Cataract Extraction.

THE very definite advantages of leaving a conjunctival bridge in ordinary cataract extraction 'are counterbalanced by certain disadvantages. It is not so easy to do an iridectomy, should that be necessary, and sometimes the delivery of the lens is so much impeded that the bridge has to be cut through. By a very slight modification in the direction of the bridge, both these difficulties are over...

Cataract extraction with the aid of alpha-chymo-trypsin.

In all cases section was made with the von Graefe knife and one to three corneoscleral sutures were inserted. Peripheral iridectomy was performed in all except two cases where the iridectomy was complete. Alpha-chymo-trypsin (A.C.T.) 1: 5000 solution was injected through the iridectomy above and posterior to the iris below. After exactly 3 minutes the anterior chamber was irrigated with saline ...
