comparative study of two silicone hydrogel contact lenses used as bandage contact lenses after photorefractive keratectomy
background: silicon hydrogel bandage contact lenses are used to enhance epithelial healing, control surface-generated pain, and prevent epithelial erosions after refractive surgery. considering the importance of faster reepithelialization in preventing complications of photorefractive keratectomy (prk) and the fact that the features and specifications of these commercially-available lenses are ...

BACKGROUND Silicon hydrogel bandage contact lenses are used to enhance epithelial healing, control surface-generated pain, and prevent epithelial erosions after refractive surgery.

متن کاملFenestrations enhance tear mixing under silicone-hydrogel contact lenses.
PURPOSE Extended wear of conventional hydrogel soft contact lenses (SCLs) is associated with adverse ocular responses. Some of these ocular events are thought to result from inadequate tear mixing in the postlens tear film (PoLTF). Therefore, strategies to increase tear mixing may improve the safety of extended-wear SCLs. Recently, it has been suggested that placing fenestrations in soft lenses...
متن کاملPredicting success with silicone-hydrogel contact lenses in new wearers.
PURPOSE to evaluate changes in tear metrics and ocular signs induced by six months of silicone-hydrogel contact lens wear and the difference in baseline characteristics between those who successfully continued in contact lens wear compared to those that did not. METHODS Non-invasive Keratograph, Tearscope and fluorescein tear break-up times (TBUTs), tear meniscus height, bulbar and limbal hyp...
متن کاملTear Deformation Time and optical quality in eyes wearing silicone hydrogel contact lenses
PURPOSE To evaluate tear film stability and optical aberrations in eyes wearing plano Lotrafilcon B contact lenses (CL). METHODS Tear Deformation Time (TDT) and aberrometric parameters were assessed in 86 normal emmetropic eyes before and 6 h after wearing CL. RESULT A statistically significant decrease in TDT and increase in root mean square (RMS) values of higher order aberrations (HOA) w...
