Corneal endothelial evaluation after phacoemulsification and silicone oil removal via an anterior approach.

Purpose: To determine the effect of simultaneous phacoemulsification and silicone oil removal via an anterior approach on the endothelial cell density (ECD).

Methods: In this prospective study, the authors measured the ECD before and 6 weeks after surgery using an automatic noncontact specular endothelial microscope. Nine patients underwent phacoemulsification and silicone oil removal via an anterior approach using a closed system and separation of irrigation/aspiration function.

Trypan blue to aid visualization of the vitreous during anterior segment surgery.

We describe the usefulness of intracameral injection of trypan blue to highlight vitreous in the anterior chamber. The technique was used in 3 eyes of 3 patients who had vitreous prolapse in the anterior chamber. Trypan blue 0.

Does a small central Nd:YAG posterior capsulotomy improve peripheral fundal visualisation for the vitreoretinal surgeon?

Background: To evaluate the effect of Nd:YAG capsulotomy for posterior capsular opacification (PCO) on visualisation of the peripheral fundus with scleral indentation.

Methods: Patients undergoing Nd:YAG capsulotomy for PCO were examined pre- and four weeks post- Nd:YAG capsulotomy. In order to give a quantitative measure of visualisation of the peripheral retina, a novel scalar measurement was developed.

Complete occlusion of the anterior capsular opening by fibrocellular membrane associated with retained silicone oil: a clinicopathologic correlation.

Background: To report the clinicopathologic features of a fibrocellular membrane in a pseudophakic eye with retained silicone oil in the absence of any capsular contraction syndrome, necessitating repeat anterior capsulorhexis.

Methods: Clinicopathologic report of a case.

Results: Histopathologic study of the membrane showed absence of any true periodic acid Schiff-positive capsule within the specimen.

Effect of the Honan intraocular pressure reducer in sub-Tenon's anesthesia.

Purpose: To ascertain whether the Honan intraocular pressure reducer (HIPR) has an effect on the preoperative intraocular pressure (IOP), surgeon's assessment of anesthesia, and patients' analgesic experience when sub-Tenon's anesthesia is used for routine cataract surgery.

Setting: Princess Alexandra Eye Pavilion, Edinburgh, Scotland.

Method: Forty-five eyes of 45 patients having routine phacoemulsification cataract surgery were randomized to receive 10 minutes of ocular compression using the HIPR or no compression after administration of sub-Tenon's anesthesia.

Patient comfort during clear corneal phacoemulsification with sub-Tenon's local anesthesia.

Purpose: To assess patient comfort with and without intravenous (i.v.) cannulation during 1-quadrant sub-Tenon's anesthesia during phacoemulsification.
