Three different techniques for photorefractive keratectomy for mixed astigmatism.

Background And Objective: To compare three different PRK techniques for the correction of mixed astigmatism.

Patients And Methods: Sixty eyes of 40 patients affected by mixed astigmatism underwent PRK using an excimer laser with three different techniques: (A) combined myopic spherical and hyperopic cylindrical treatment (mean attempted correction in defocus equivalent [DE], 2 +/- 0.4 D), (B) combined cross-cylinder and spherical equivalent treatment (mean attempted correction in DE, 2.

Photorefractive keratectomy and LASIK for the correction of hyperopia: 2-year follow-up.

Purpose: To evaluate the efficacy and safety of photorefractive keratectomy (PRK) and LASIK in the correction of hyperopia.

Methods: A retrospective study was conducted on 100 eyes of 56 patients with a mean hyperopia of +2.85 +/- 1.

Photorefractive keratectomy and laser in situ keratomileusis in refractive accommodative esotropia.

Purpose: To evaluate the efficacy of excimer laser refractive surgery as an alternative for optical correction in patients affected by fully refractive accommodative strabismus.

Setting: Eye Clinic, University of L'Aquila, L'Aquila, Italy.

Methods: After a simulation of the cycloplegic correction with contact lenses over a 30-day period, 18 patients (6 men, 12 women, mean age 32.
