Atlas corneal topography

Patients were instructed to instill tobramycin with dexamethasone (Tobradex; Alcon Laboratories, Inc., Fort Worth, TX) and ofloxacin (Exocin; Allergan Ltd, Marlow, UK) four times daily and wear plastic shields for sleeping during the first week. The surgeon reviewed the patient at day 1 and flap adjustments were performed if necessary at the slit-lamp using a surgical spear under topical anesthetic and antibiotic cover. An in-house optometrist examined the patient at 1, 3, and 12 months and yearly thereafter with surgeon review for all outliers. All visits included monocular and binocular UDVA, manifest refraction, and CDVA. Best spectacle-corrected mesopic contrast sensitivity, ATLAS corneal topography and dilated WASCA aberrometry (both Carl Zeiss Meditec) were performed at 3 months, 1 year, and 2 years.
Postoperative complications and dry eye symptoms were assessed at each visit. A 6-grade classification system was used for each parameter: trace, GD I-II (not visually significant), and GD III-V. In this scale, trace refers to any small amount inconsistent with an untreated cornea, even if not visually significant.

Patients were instructed to instill tobramycin & dexamethasone (Tobradex: Alcon, Fort Worth, TX, USA) and ofloxacin (Exocin: Allergan Ltd, Marlow, UK) four times daily and wear plastic shields for sleeping during the first week. The surgeon reviewed the patient at day one and measured spherical refraction and uncorrected distance visual acuity (UDVA); if necessary, flap adjustments were performed at the slit-lamp using a surgical spear under topical anesthetic and antibiotic cover. An optometrist examined the patient at one, three, and twelve months and then yearly thereafter. All visits included measurements of monocular and binocular UDVA, manifest refraction, and corrected distance visual acuity (CDVA). Best-spectacle-corrected mesopic contrast sensitivity was performed at the 3 month visit to compare to baseline. ATLAS corneal topography (Carl Zeiss Meditec, Jena, Germany) and WASCA aberrometry (Carl Zeiss Meditec, Jena, Germany) were performed at 3 months, 1 year and 2 years.
