Photoastigmatic Refractive Keratectomy for Compound Myopic Astigmatism with a Nidek Laser

Journal of Refractive Surgery, 1997
ABSTRACT BACKGROUND: With advances in the delivery of excimer laser energy to the cornea, spherocylindrical ablations are now possible. The refractive and visual outcome of eyes undergoing photoastigmatic refractive keratectomy with a minimum of 12 months follow-up are presented.

Photoastigmatic refractive keratectomy in 168 eyes: Six-month results

Journal of Cataract and Refractive Surgery, 1994
Using a 193 nm excimer laser, we performed elliptical astigmatic and spherical corneal ablation on 168 eyes with compound myopic astigmatism and analyzed the three- and six-month postoperative results. Mean preoperative astigmatism was 1.51 +/- 0.81 diopters (D).

Photoastigmatic refractive keratectomy for primary treatment and revision of myopic astigmatism

Journal of Cataract and Refractive Surgery, 1997
To evaluate the results in 43 eyes treated with a rotating mask for myopic astigmatism and followed for up to 1 year.Lucerne Eye Clinic, Cantonal Hospital, Lucerne, Switzerland.Thirty-two patients (42 eyes) were selected to have photoastigmatic refractive keratectomy (PARK). In 33% (14 eyes), this treatment was the second or third ablation.
