Case ReportsRetained contact lens for more than 10 years in a laser in situ keratomileusis patient.
A 49-year-old man with blurred vision in 1 eye and myopic regression had laser in situ keratomileusis (LASIK) in the right eye after having 20/20 uncorrected visual acuity for 2 years. At the conclusion of surgery, a poly(methyl methacrylate) contact lens that had been retained for more than 10 years was discovered in the upper fornix. ⋯ In addition, retained contact lenses, lid lesions, and periocular masses can induce refractive and topographic changes after LASIK. The retained contact lens may have led to compression-induced changes in corneal curvature, resulting in the need for uniocular enhancement 2 years after the primary LASIK procedure.

Randomized Controlled Trial Comparative Study Clinical TrialLaser-assisted subepithelial keratectomy and photorefractive keratectomy for the correction of hyperopia. Results of a 2-year follow-up.
To evaluate and compare the efficacy, safety, predictability, and stability of laser-assisted subepithelial keratectomy (LASEK) and photorefractive keratectomy (PRK) for low to moderate hyperopia with a 2-year follow-up. ⋯ Laser-assisted subepithelial keratectomy for hyperopia up to +5.00 D provided good visual and refractive results. It significantly reduced postoperative pain, grade of peripheral ring-shaped corneal haze, and regression of hyperopia. Hyperopic LASEK provided quicker visual recovery and achieved better efficacy, predictability, and refractive stability than hyperopic PRK.
