Randomized Controlled Trial Comparative Study
Comparison of the effects of dorzolamide-timolol fixed combination and brimonidine on intraocular pressure after phacoemulsification surgery.
To compare the effects of dorzolamide-timolol combination and brimonidine on intraocular pressure (IOP) after phacoemulsification surgery. ⋯ Prophylactic treatment with dorzolamide-timolol fixed combination was more effective than brimonidine in reducing IOP 6 hours and 24 hours after phacoemulsification surgery.

Comparative Study
A comparative study of the impact of certified and noncertified ophthalmic medical personnel on practice quality and productivity.
To compare ophthalmic practice productivity and performance attributes, as rated by employing ophthalmologists, of noncertified and three levels of certified ophthalmic medical personnel. ⋯ Compared to noncertified personnel, the employment of certified ophthalmic personnel enhances the quality and productivity of an ophthalmic practice. Overall practice productivity is increased with certified ophthalmic medical personnel.

Recent outbreaks of microbial keratitis in contact lens wearers have involved various pathogens, including Acanthamoeba and Fusarium species. Specific reasons for the marked increase in microbial keratitis, particularly those involving species typically rarely involved in contact lens infection, remain unknown. ⋯ Although there is some conflict of opinion in the literature regarding the necessity for a mechanical rub during lens cleaning and disinfection, growing evidence supports the reestablishment of a digital rub component to multipurpose solution lens care systems. This article reviews the literature on whether such a process should be recommended to contact lens wearers.

To report and define the clinical presentation, hygienic practices, treatment regimens, and visual sequelae of contact lens wearers infected with Fusarium keratitis in the New York City metropolitan area and to review the literature on Fusarium keratitis. ⋯ A delay in diagnosis and prolonged treatment delay of Fusarium keratitis is associated with significant comorbidity. Physicians must have a higher index of suspicion for fungal keratitis in contact lens wearers to facilitate in early diagnosis and treatment.

Randomized Controlled Trial
Adverse events and discontinuations during 18 months of silicone hydrogel contact lens wear.
To report differences in the incidence of adverse events and discontinuations found in a group of neophyte contact wearers using two different silicone hydrogel contact lenses on a daily- and continuous-wear basis during an 18-month period. ⋯ Lotrafilcon A lenses were associated with a higher incidence of adverse events than balafilcon A lenses were, and this difference is attributed to the difference in the incidence of corneal infiltrative events. Subjects wearing lenses on a daily-wear basis had fewer adverse events than did subjects wearing lenses on a continuous-wear basis. Both lens types and wearing regimens showed a similar incidence of discontinuations.
