Loteprednol vs. Prednisolone and Fluorometholone
Completed · Phase 4
Conditions studied: Intraocular Pressure, Corneal Opacity
In brief
Corneal haze, in which the cornea becomes cloudy, is a well-known and a potentially vision-threatening postoperative complication of photorefractive keratectomy (PRK). Topical ophthalmic corticosteroids are routinely prescribed by most surgeons postoperatively to help prevent this complication. Goals of topical steroids use after PRK include effective modulation of the healing response to prevent corneal haze while at the same time minimizing side effects, such as intraocular pressure elevation or cataract formation. Loteprednol etabonate is a corticosteroid that exerts its therapeutic effects and is then quickly changed into inactive metabolites. This relatively fast metabolism of loteprednol gives it a lower side effect profile than other steroids, including a smaller effect on intraocular pressure. In the ophthalmic literature, there is currently no consensus on a standard regimen or which type of corticosteroid should be used after PRK. Investigators are conducting a prospective, randomized trial to compare the incidence of intraocular pressure rise and visually significant postoperative corneal haze after PRK with the use of loteprednol 0.5% gel compared to the use of earlier generation steroids, prednisolone acetate 1% suspension and fluorometholone 0.1% suspension.

You may qualify if…
- All subjects who are deemed suitable candidates for PRK after routine refractive surgery screening will be considered eligible for participation in this study.
- Subjects must be at least 21 years of age and not pregnant or nursing (due to fluctuations in visual parameters during pregnancy).
You may not qualify if…
- Selection will be consistent with the current standard of care for PRK. Any patient that is not a suitable candidate for PRK will not be included.
