Corneal inlay improves near vision in two studies
 Vladimir Feingold |
PRAGUE — A corneal inlay was shown to recover near vision in two studies presented here.
"All our 64 patients were J5 or worse before surgery and had to wear spectacles for reading. After implantation of the lens, they had a dramatic improvement in near vision, gaining a mean of six Snellen lines, up to 12 lines in some cases," Vladimir Feingold, who developed the Flexivue intracorneal Microlens (Presbia) and is the chief technology officer of Presbia, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
A loss of about two lines of uncorrected distance visual acuity was reported, but due to the induction of spherical aberration, all patients reported satisfaction with their binocular distance vision and 97% reported satisfaction with their near vision.
Spectacle independence was achieved in 78% of patients. Follow-up was 1 year.
Ioannis Pallikaris, MD, who has 4 years of experience with the Flexivue Microlens, recently tried the IntraLase iPockets software (Abbott Medical Optics), which eliminates the need for a mask when creating the lens tunnel. "The new software allows the surgeon to easily tailor the pocket's dimensions, varying width, length and depth, choosing the entrance point," he said.
After more than 1 year of follow-up with 40 patients, uncorrected near vision between 20/30 and 20/20 was achieved in 82% of patients. Uncorrected distance vision was 20/32 in the operated eye and 20/20 binocularly.
