Dry eye after LASIK: comparison of outcomes for Asian and Caucasian eyes.

Background: Dry eye is a common complication of LASIK surgery. Our clinical impression was that post-LASIK dry eye was more problematic for our Asian patients. The aim of this study was to determine if dry eye after LASIK is more prevalent, more sustained and more severe in Asian eyes compared with Caucasian eyes.

Wavefront aberrations following laser in situ keratomileusis and refractive lens exchange for hypermetropia.

Purpose: To compare the magnitude of aberrations in eyes after elective hypermetropic laser in situ keratomileusis (LASIK) and refractive lens exchange (clear lens replacement).

Methods: Forty-nine patients (92 eyes) had hypermetropic LASIK and 28 (48 eyes) had refractive lens exchange; 23 hypermetropic subjects (41 eyes) were the control group. LASIK was performed with the Nidek EC-5000 excimer laser; ablation zones 5.

Chronic dry eye and regression after laser in situ keratomileusis for myopia.

Purpose: To examine the relationship between chronic dry eye and refractive regression after laser in situ keratomileusis (LASIK) for myopia.

Setting: Excimer Laser Vision Centre and Centre for Eye Research, Queensland University of Technology, Brisbane, Australia.

Methods: This study was based on a retrospective analysis of a clinical database and a case study series.

Ocular surface management of photorefractive keratectomy and laser in situ keratomileusis.

Purpose: To examine the effects of keratorefractive surgery and ocular surface management on goblet cell density, dry eye symptom incidence, and spherical equivalent refraction.

Methods: We performed a retrospective analysis of four myopia groups: Untreated controls (n = 53); PRK (n = 51); LASIK without ocular surface management (n = 56); LASIK with ocular surface management (n = 140). Ocular surface management involved the routine use of non-preserved artificial tears and other lubricants before, during, and after surgery.

Effect of laser in situ keratomileusis for hyperopia on tear film and ocular surface.

Purpose: To examine the effects of laser in situ keratomileusis (LASIK) for hyperopia on the tear film and ocular surface.

Methods: A retrospective 12-month analysis of 88 eyes (88 participants) who had LASIK for hyperopia was performed. Participants were evaluated before and after (2 weeks, 1, 3, 6, and 12 months) surgery for dry eye symptoms (McMonnies Dry Eye Survey primary symptoms), tear film stability (fluorescein break-up time), tear volume (phenol red thread test), ocular surface staining (fluorescein), and conjunctival goblet cell density.
