Summary
Hyperopic photorefractive keratectomy (PRK) using an excimer laser achieved good results, with 60% of patients within +/-1.0D correction after 6 months. Different masks showed no significant impact on outcomes.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- Hyperopic photorefractive keratectomy (PRK) is a surgical option for correcting farsightedness.
- Excimer laser technology has advanced refractive surgery techniques.
Purpose of the Study:
- To analyze clinical outcomes of hyperopic PRK.
- To compare the efficacy of different masks used during PRK procedures.
Main Methods:
- Treatment of 20 eyes from 16 hyperopic patients using an Aesculap-Meditec MEL60 excimer laser.
- Follow-up duration averaged 9.9 months.
- Statistical comparison between two masks using the unpaired Student t-test.
Main Results:
- Mean spherical equivalent improved from +4.23D preoperatively to +1.23D at final follow-up.
- 60% of eyes achieved a spherical equivalent within +/-1.0D of attempted correction by 6 months.
- No statistically significant difference in outcomes was observed between the two masks used.
Conclusions:
- Hyperopic PRK can yield good clinical results.
- Patient preparation is crucial for successful PRK outcomes.
- Mask selection did not significantly influence the refractive results.
