Objective: To compare the anatomical and functional outcome of scleral buckle (SB) surgery with that of pars plana vitrectomy (PPV) alone in the treatment of primary rhegmatogenous pseudophakic retinal detachment (RD).

Methods: In this prospective, randomized clinical trial, 150 eyes of 150 patients with pseudophakic RD and proliferative vitreoretinopathy (PVR) stage B or less were randomized to SB surgery (75 eyes) or primary PPV (75 eyes). SB surgery involved break localization, cryotherapy, placement of a circumferential 240 style 2.

Purpose: We evaluated the safety and efficacy of the non-contact holmium:YAG laser thermal keratoplasty (LTK) for the treatment of mild to moderate hyperopia without astigmatism.

Methods: A prospective, non-comparative case series included 50 eyes of 28 patients (aged > or =40 years) who had stable refraction and an astigmatic component < +0.50 diopters (D).

Purpose: To compare the incidence of posterior capsule rupture and vitreous loss during phacoemulsification with and without the use of an anterior chamber maintainer (ACM) SETTING: Aristotle University Eye Clinic, Thessaloniki, Greece.

Methods: The surgical records of patients who had phacoemulsification by experienced surgeons over a 2-year period were reviewed. The cases were divided into 2 groups: surgery performed without the use of an ACM (no-ACM group) and surgery performed with the use of an ACM (ACM group).

Purpose: To evaluate the efficacy of pars plana vitrectomy in conjunction with intraoperative perfluoro-n-octane (PFO) use as initial treatment of retinal detachment (RD) with multiple breaks located at various distances from the ora serrata.

Methods: Twenty-two consecutive eyes (15 phakic, 2 aphakic, and 5 pseudophakic) presenting with RD with multiple breaks and tears underwent primary pars plana vitrectomy, PFO retinal reattachment, transcleral cryopexy or endolaser treatment of breaks, PFO/air exchange, and final injection of 18% perfluoropropane (C3F8). Scleral buckles were not used.

Purpose: To study the echographic appearance of various types of senile cataracts using a-scan quantitative echography and correlate these findings with phacoemulsification parameters indicating surgical lens hardness.

Methods: The study involved 71 eyes with senile cataracts and 20 additional eyes with normal human lenses. Cataract and clear lenses were studied using A-scan quantitative echography and with a tissue sensitivity gain setting of 74 db.

Purpose: To demonstrate the advantages and efficacy of internal limiting membrane removal under perfluorocarbon liquid in macular-hole-associated retinal detachment.

Design: Interventional case series.

Method: Four patients with macular-hole-associated retinal detachment underwent pars plana vitrectomy, retinal reattachment with endodrainage through the macular hole, perfluoro-n-octane injection to seal the macular hole, indocyanine green injection under the perfluoro-n-octane bubble and removal of the indocyanine green-stained internal limiting membrane.

Purpose: To evaluate the efficacy and safety of topical mitomycin C (MMC) for conjunctival-corneal intraepithelial neoplasia (CCIN).

Methods: One patient with primary CCIN received seven applications for 3 minutes of mitomycin C 0.02%, for 2 weeks, on alternative days.
