Hyperopia: Limits in Corneal Refractive Surgery Setting
Evaluation of the limit for hyperopia in corneal refractive surgery.
Thirty-three hyperopic eyes more than +2.5 D were operated with LASIK. LASIK-Cut was done with Carriazzo-Barraquer Microkeratome (10 mm flap diameter, 130 mµ flap-thickness. Pre- and postoperative, 3, and 6 moths and 1 year retrospective were analyzed in stability, safety, predictability.
There were under corrections in predictability more than +5 D, small regression in stability. No loss of lines and gaining 2 lines in safety .97% had a visual acuity from 20/40 or better. Complications: small regression, epithelial ingrowth.
LASIK in hyperopia up to +5 D had a good stability, safety and predictability for eyes with K-value less than 47 D and radius more than 7.4 mm.
