Abstract
Purpose:
To evaluate the effect of seasonal factors on the final refractive outcome following excimer laser photorefractive keratectomy (PRK).
Methods:
We examined the final refractive outcome for 5367 patients who had undergone PRK and photoastigmatic refractive keratectomy (PARK) over an 18-month period, April 1994 to August 1995, with a Nidek EC-5000 excimer laser and analyzed them by monthly and seasonal groups at time of treatment.
Results:
We were unable to demonstrate any significant difference in patients grouped according to season at time of treatment.
Conclusion:
We would not recommend any seasonal-related adjustment for treatment with the Nidek EC-5000 excimer laser.
