Posterior vitreous detachment and retinal detachment after implantation of the Visian phakic implantable collamer lens.

Introduction: To evaluate the vitreoretinal complications in myopes after Visian implantable collamer lenses (ICL) implantation.

Materials And Methods: This is a retrospective, observational, non-comparative clinical study that evaluated 617 consecutive myopes who underwent ICL implantation at the Department of Refractive Surgery, Yemen Magrabi Hospital, Sana'a, Yemen between July 2006 and May 2010. Follow up ranged from 6 months to 40 months.

Phacoviscocanalostomy in pseudoexfoliation glaucoma versus primary open-angle glaucoma.

Objective: To compare the outcome of phacoviscocanalostomy in pseudoexfoliation glaucoma (PEXG) versus that in primary open-angle glaucoma (POAG).

Design: Prospective comparative study.

Participants: Sixty eyes of 60 patients who underwent phacoviscocanalostomy for cataract and medically uncontrolled PEXG (30 eyes) or POAG (30 eyes).

Reasons for not performing keratorefractive surgery in patients seeking refractive surgery in a hospital-based cohort in "yemen".

Background: To determine and analyze the reasons why keratorefractive surgery, laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) were not performed in patients who presented for refractive surgery consultation.

Materials And Methods: A retrospective observational study was performed between January 2006 and December 2007 in the Yemen Magrabi Hospital. The case records of 2,091 consecutive new patients who presented for refractive surgery were reviewed.

Vitreoretinal complications in Yemeni patients with keratorefractive surgery.

Objective: To evaluate vitreoretinal complications in patients undergoing laser keratorefractive surgery.

Methods: This retrospective observational non-comparative clinical study was carried out between June 2005 and March 2008, and included 4691 consecutive laser keratorefractive surgery procedures for 2480 patients performed in the Department of Refractive Surgery, Yemen Magrabi Hospital, Sana'a, Yemen. Patients were followed up for 12-36 months.

Intraoperative and early postoperative complications of laser in situ keratomileusis in Yemen.

Objective: To determine the intraoperative and early postoperative complications and visual outcome of laser in situ keratomileusis (LASIK) surgery for the correction of myopia.

Methods: The first 2000 consecutive myopic LASIK eyes operated at the Department of Refractive Surgery, Yemen Magrabi Hospital, Sana'a, Yemen from June 2005 to October 2006 were the study group. This is a retrospective observational noncomparative clinical study.

Changes in keratoconic corneas after intracorneal ring segment explantation and reimplantation.

Purpose: To evaluate the outcome and potential reversibility of the changes induced in keratoconic eyes after intracorneal ring segment explantation.

Design: Retrospective, interventional case series.

Participants: Five eyes of 4 patients who underwent uneventful implantation of one or two intracorneal ring segment segments for the correction of clear corneal keratoconus and who required explantation of one segment due to complications.
