摘要：Purpose. Re.sons for the.lack of succe.s for contact le.s patie.ts range.from poor fit, to discomfort or to a le.s than optimum we.ring sche.ule. This proje.t was a pre.iminary inve.tigation of customize. soft toric contact le.se. as an alte.native.for unsucce.sful contact le.s patie.ts or pote.tial drop-outs. Me.hods: Fifte.n he.lthy non-compromise., pre.iously unsucce.sful contact le.s we.ring patie.ts (13 wome., 2 me.) with age. from 21 to 33 ye.rs (25.1 ± 2.7 ye.rs) we.e.the.subje.ts for this study. The. we.e.e.pirically fitte. with 15 astigmatic and 5 sphe.ical customize. Spe.iale.e. soft contact le.se.. Visual acuitie., comfort, le.s move.e.t, and rotation we.e.e.aluate.. Re.ults: Patie.ts fitte. with customize. Spe.iale.e. soft contact le.se. had statistically significant be.te. visual acuitie. than with Phoropte. Manife.t Re.raction. The.le.se. use. in this study ce.te.e. we.l and move. no more.than 1 mm upon e.ch blink. Le.s rotation was le.s than 10 de.re.s for all toric le.se.. Patie.ts gave.ve.y positive.vision and comfort ratings. Conclusion: This pre.iminary study supports the.application of a software.program to e.pirically de.ign and manufacture.Spe.ial e.e. custom soft le.se. base. upon corne.l topographical parame.e.s and subje.tive.manife.t re.raction for those.patie.ts who e.the. have.challe.ging corne.l parame.e.s, high sphe.o-cylindrical pre.criptions, or are.curre.tly dissatisfie. with the.r contact le.se. and are.pote.tial drop-outs.
