Radial keratotomy for residual myopia after photorefractive keratectomy.

Purpose: To evaluate the safety, efficacy, and complications of radial keratotomy (RK) after photorefractive keratectomy (PRK) for myopia.

Setting: Laser Ultravision Institute. Montreal, Canada.

Arcuate keratotomy to correct naturally occurring astigmatism.

Purpose: To evaluate retrospectively the safety, efficacy, and complications of arcuate keratotomy (AK) in correcting naturally occurring astigmatism.

Setting: Laser Ultravision Institute, Montreal, Canada.

Methods: Surgically induced refractive change was evaluated in 25 eyes of 15 patients with naturally occurring astigmatism.

Excimer laser photorefractive keratectomy: one year follow-up.

Background And Objective: To confirm the effectiveness of the 193 nm excimer laser to correct low myopia (1.00 to 6.00 D), moderate myopia (6.

Excimer photorefractive keratectomy after undercorrected radial keratotomy.

Radial keratotomy has been used for the treatment of myopia since 1979. Until recently, patients with undercorrected myopia had recourse only to repeated keratotomy. Now patients undercorrected after two or more radial keratotomy procedures can be treated with the excimer laser to reduce the residual myopia.
