AIM: To compare the clinical performance of two types of silicon hydrogel contact lenses used as bandage lenses after LASEK surgery. METHODS: A prospective, double-masked study was conducted on 42 eyes of 21 patients who received binocular LASEK surgeries. The interocular difference in spherical equivalent power was less than -1.50D. Patients were randomly assigned to wear Galyfilcon A (lens A) bandage contact lens in one eye and Balafilcon A (lens B) in the fellow eye after the surgery. The responses to a subjective questionnaire on comfort of wearing, corneal epithelial status, conjunctival hyperemia, limbal neovascularization, lens fitting and contact lens debris were assessed 1 and 5 days postoperatively. Corneal endothelium was assessed before and 5 days after the surgery upon bandage lens removal. RESULTS: There was no difference between the two groups in terms of conjunctival hyperemia, limbal neovascularization, contact lens fitting, corneal epithelial status, corneal endothelium cell density (CD) and endothelium cell size (CS) at any postoperative visit. Complaints of discomfort, including foreign body sensation, pain and intolerance were statistically more among lens B wearers at any postoperative visit (P lens B appeared to attract much more debris than lens A at the 5-day post-operative follow-up visit (P lenses investigated in this study demonstrated similar clinical performance in terms of corneal responses and lens fitting. However, lens A showed a better performance in terms of comfort of wearing and deposit resistance.

BACKGROUND This study describes the use of a moisture chamber to treat corneal ulceration due to temporary lagophthalmos in a critically ill *** SUMMARY A 46-year-old woman was admitted to the intensive care unit after a car *** suffered multiple injuries that included brain injury and presented with moderately decreased consciousness and lagophthalmos in her right *** 6 d,her consciousness improved considerably;at which time,exposure keratopathy occurred and worsened to corneal *** gel,antibiotic ointment,and bandage contact lens were all ineffective in preventing or treating the exposure *** of tarsorrhaphy,a moisture chamber was applied which successfully controlled the corneal *** moisture chamber was discontinued when complete eyelid closure recovered a week *** A moisture chamber may be an effective,noninvasive alternative to tarsorrhaphy for treating severe exposure keratopathy due to temporary lagophthalmos.
