Outcomes of the Haigis-L formula for calculating intraocular lens power in Asian eyes after refractive surgery.

Purpose: To report outcomes using the Haigis-L formula to calculate intraocular lens (IOL) power in Asian eyes with long axial lengths (ALs) that had previous myopic laser in situ keratomileusis (LASIK) or photorefractive keratectomy (PRK).

Setting: Singapore National Eye Centre, Singapore.

Design: Retrospective case series.

Cystoid macular edema in acute presentation of central retinal artery occlusion.

A seventy-six-year-old lady with poor vision of the left eye due to previous retinal detachment presented with acute visual loss of her right eye secondary to central retinal artery occlusion.

To determine practice preference of prophylaxis against post-cataract surgery endophthalmitis in Singapore. Prospective nationwide survey of all registered ophthalmologists through telephone, e-mail or postal questionnaires. A response rate of 76.

Comparison of outcomes of lamellar keratoplasty and penetrating keratoplasty in keratoconus.

Purpose: To compare outcomes after penetrating keratoplasty (PK) and two techniques of deep anterior lamellar keratoplasty (DALK) in patients with keratoconus.

Design: Retrospective cohort study.

Methods: One hundred and twenty-five corneal transplantations comprising 100 PK and 25 DALK procedures for keratoconus at the Singapore National Eye Centre from April 1992 through December 2006 were included.
