FT LAUDERDALE / Lasik patients who wore soft contact for vision
correction prior to surgery had better outcomes, according to a
study presented at the annual meeting of the Association for Research
in Vision and Ophthalmology.
The study was presented by Kuang-mon Ashley Tuan, OD, PhD, principal
research scientist for Advanced Medical Optics (AMO). The study
was designed to determine if physiologic changes from soft contact
lenses could affect Lasik outcomes.
Dr. Tuan conducted a retrospective study of the six-month outcomes
from 156 eyes that were treated with Visx CustomVue wavefront-guided
Lasik as a part of a US Food and Drug Administration clinical trial.
Patients were selected to provide a representative sample. Length
of contact lens use, age, sex, race, corneal thickness, and other
preoperative factors were considered.
Six month follow-up post-Lasik data showed that the soft contact
lens group had a smaller degree of spherical refractive error than
spectacle wearers: -0.03 diopters compared to +0.35 diopters in
the spectacle group.
