Effect of aging on optical quality and intraocular scattering using the double-pass instrument.

Purpose: To assess the effect of aging on optical quality in a normal population.

Methods: We prospectively examined 100 normal eyes of 100 healthy volunteers (50 men, 50 women; ages, 20-69 years; mean age ± standard deviation, 44.6 ± 15.

Factors influencing the changes in coma-like aberrations after myopic laser in situ keratomileusis.

Purpose: To assess factors affecting changes in coma-like aberrations after myopic laser in situ keratomileusis (LASIK).

Methods: We retrospectively examined 91 eyes of 48 patients undergoing LASIK (mean patient age ± standard deviation, 29.6 ± 8.

Clinical outcomes of photoastigmatic refractive keratectomy for the correction of residual refractive errors following cataract surgery.

Purpose: To assess the clinical outcomes of photoastigmatic refractive keratectomy (PARK) for the correction of residual refractive errors after cataract surgery.

Methods: This study evaluated 88 eyes of 66 consecutive patients with mean spherical equivalent refraction of -3.16±1.
