Vision stable with PRK out to 14 years, study finds (ASN SuperSite, June, 2009)

A majority of patients followed to 14 years after PRK were satisfied with their refractive correction and maintained vision at least equal to preoperative values, according to a study.

After 14 years, manifest refraction spherical equivalent was –0.17 D in the low myopia group and –0.67 D in the high myopia group. Uncorrected visual acuity was –0.06 logMAR in the low myopia group and –0.11 logMAR in the high myopia group. Best corrected visual acuity was 0.00 logMAR in the low myopia group and –0.03 in the high myopia group.

“At the end of follow-up, 97% eyes of the low myopia group and 94% of the high myopia group had clear corneas,” the authors said.

There were no late complications noted in the study.

Dr Nurfifi Arliani’s comment on the story: “I reviewed more than 500 eyes after 3 years of Advanced Surface Ablation and found the same result. Most doctors in my clinic prefer doing ASA than Lasik with metal blade.”
