Unilateral amiodarone keratopathy.

Vortex keratopathy is characterized by bilateral symmetrical superficial corneal deposits in a vortex pattern. It is the most common ocular finding among patients being treated with amiodarone. An unusual case of unilateral amiodarone vortex keratopathy in an elderly woman with corneal dysplasia in the second eye is presented.

Amadeus microkeratome: experience with the first 2000 cases and lessons learned.

Background: To assess the safety and efficacy of the Amadeus microkeratome and to report on lessons learnt in optimizing results from its use.

Methods: A retrospective review of the flap-related complications of 2000 laser in situ keratomileusis (LASIK) procedures performed by one surgeon using the Amadeus microkeratome (AMO, Irvine, CA, USA) was conducted. One hundred consecutive cases had preoperative and intraoperative pachymetry to evaluate the relationship between flap thickness, corneal thickness and reuse of the blade.

Comparison of the Zeiss IOLMaster and applanation A-scan ultrasound: biometry for intraocular lens calculation.

Purpose: A comparison of axial length estimates using applanation A-scan ultrasound and the Zeiss IOLMaster was conducted. The accuracy in predicting postoperative refraction determined by each method was also compared.

Methods: A cross-sectional study was performed on 51 eyes in 46 patients presenting to clinical practice for cataract surgery assessment.
