BERLIN — Laser refractive surgery is an effective means of treating residual ametropia after cataract surgery and IOL implantation, a surgeon said here.

Anna M. Roszkowska, MD, PhD, and colleagues found that excimer laser was successful in eyes that had different residual refractive errors after cataract surgery.

"Normal corneal healing was observed in all patients, elderly and young alike, so this kind of treatment can be taken into consideration in patients with IOL implantation and ametropia," she said at the European Society of Cataract and Refractive Surgeons meeting.

Dr. Roszkowska and colleagues studied 14 eyes of 13 patients, aged 43 to 82 years old, who had previous cataract surgery. Ten eyes had incorrect IOL calculation, and four eyes had surgically induced astigmatism.

In the study, patients underwent PRK with the MEL 70 excimer laser (Carl Zeiss Meditec). Follow-up was 1 to 3 years.

Dr. Roszkowska and colleagues found significant improvement in both uncorrected and best corrected visual acuity. Patients showed no adverse effects, corneal haze or ocular hypertension.
