Safety and Efficacy of Lotemax Versus FML in Subjects Undergoing PRK for the Correction of Mild to Moderate Myopia, 3- Month Follow-up Study
Randomized, Single Blinded Controlled Trial for Evaluation of the Safety and Efficacy of Loteprednol Versus Fluorometholone After Photorefractive Keratectomy for the Correction of Mild to Moderate Myopia, 3- Month Follow-up Study
STUDY OBJECTIVE: To evaluate and compare the safety and efficacy of (corneal Wound Healing and Intraocular Pressure) Fluorometholone and Loteprednol after photorefractive keratectomy (PRK) surgery.
OVERALL STUDY DESIGN: Structure: Single-center, randomized, single blinded, contralateral (one eye receives FML, one eye Lotemax) Treatment Group: Patients will be randomized to the eye and will receive FML in one eye, Lotemax in contralateral eye Duration: 3 months Dosage/Dose Regimen: All patients will receive each one of the steroid agents 4 x a day for one month, 3 x a day for one month and 2 x a day for one month Study medication will be administered to the randomized eye through post op days according to mention protocol. Visit Schedule: baseline-screening, postop days 1, 7, 30 and then month 3th (through corneal re-epithelialization).

- Refractive error -1 to -8 diopters (spherical equivalent) at baseline
- Females of childbearing age must have a negative pregnancy test result at baseline. A female considered to be of non-childbearing potential is she is postmenopausal (no menses for 12 consecutive months) or is without a uterus.
- Ability to follow study instructions and likely to complete the entire course of the study(Subjects who are able to comply with all study procedures, including wearing a soft bandage contact lens in the immediate postoperative period. )
- Written informed consent will be obtained
- Written HIPPA authorization will be obtained
- Subjects with MRSE <6.0 D, with less than 2.0 D of astigmatism.
- Stable prescription in both eyes as defined by <0.25 D change over the preceding 2 years.
Exclusion Criteria:
- Uncontrolled systemic disease you mean if someone has controlled DM or rheumatic disease can be included
- Any active ocular disease, corneal abnormalities, lid abnormalities, or any ocular pathologies
- History of serious eye disease, trauma, or previous ocular surgery
- History of unstable myopia
- History of herpes keratitis
- Known allergy or hypersensitivity to the study medication
- Anticipated wearing of contact lenses in addition to the required bandage contact lens post-PRK. Patients who wear soft contact lenses should discontinue wearing them at least 7 days prior to baseline visit. Patients wearing RGP or hard contact lenses should discontinue wearing them at least 3 weeks prior to baseline visit.
- Females who are pregnant, breastfeeding, or trying to conceive.
- Keratoconus or keratoconus suspect
- Any condition or situation which, in the investigator's opinion, may put patient at significant risk or may confound the study results
- Subjects who have a past or present disease, which as judged by the investigator may affect the safety of the subject or the outcome of the study.
- Subjects who have previously had corneal surgery.
Subjects with any ocular disease or corneal abnormality, including but not limited to:
- Decreased corneal sensation / neurotrophic cornea;
- Corneal vascularization;
- Keratoconus;
- Keratoconjunctivitis sicca requiring chronic treatment;
- Lagophthalmos;
- Blepharitis;
- History of infectious keratitis;
- History of glaucoma or intraocular pressure of >21 mmHg or use of glaucoma medications;
- Significant dry eye disease that requires regular topical treatment;
- Corneal thickness <480 µm at the thinnest point, and
- Posterior elevation >40 micron.
