Conductive keratoplasty has good results for hyperopia at 6 months

NICE, France — Conductive keratoplasty appears to be a safe and effective technique for the correction of low hyperopia and hyperopic astigmatism, at least at the 6-month mark, according to a study presented here.
“The procedure seems to be safe, and the results of uncorrected visual acuity are stable up to the 6-month period,” said Ioannis Pallikaris, MD, at the European Society of Cataract and Refractive Surgeons meeting.
In the study, conducted at the University of Crete Medical School, 39 eyes in 18 men and 21 women were treated for low hyperopia of up to +3.25 D and astigmatism of up to –5.75 D.
“In the surgery, we treated the spherical component first. We used the straddling technique. The laser spots were put on the flat meridian of the astigmatism,” Dr. Pallikaris explained.
At 6-month follow-up, mean uncorrected vision improved from 20/40 preop to 20/25, he said. “We were very happy to see that that no one lost lines of acuity, and five eyes gained 1 line of best-corrected visual acuity,” he said.
The manifest spherical equivalent refraction also improved at the 6-month mark, from mean +1.5 D preop to a mean of –0.31 D for all eyes.
“We expect these numbers to remain stable, and the use of conductive keratoplasty to become a viable option for those with naturally occurring and induced hyperopia and hyperopic astigmatism,” Dr. Pallikaris said.
