Summary
Clear lens extraction with intraocular lens implantation effectively corrects hyperopia. This safe and predictable procedure significantly improves uncorrected and best-corrected visual acuity in patients.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- Hyperopia correction is a significant challenge in refractive surgery.
- Clear lens extraction (CLE) offers a refractive correction option for hyperopic eyes.
Purpose of the Study:
- To evaluate the safety, predictability, and effectiveness of clear lens extraction (CLE) with posterior chamber intraocular lens (IOL) implantation for hyperopia correction.
Main Methods:
- Prospective study of 20 hyperopic eyes in 12 patients (ages 19-50).
- Clear lens extraction with posterior chamber IOL implantation.
- Holladay 2 formula used for IOL power calculation.
- Peripheral iridectomy performed in 5 patients with occludable angles.
Main Results:
- Mean hyperopic refraction: +6.66 D.
- Mean follow-up: 16.96 months.
- Mean uncorrected visual acuity improved by 3 Snellen lines.
- Mean best-corrected visual acuity improved by 1 Snellen line.
- 70% of patients achieved refraction within +/-0.50 D of target.
Conclusions:
- Clear lens extraction with posterior chamber IOL implantation is a safe and effective method for hyperopia correction.
- The procedure demonstrates good predictability in refractive outcomes.
- Significant visual acuity improvements were observed postoperatively.
