Summary
Intraocular lens (IOL) implantation in highly myopic patients with long axial lengths showed comparable complication rates to cataract surgery alone. Most pseudophakic patients achieved good visual acuity and did not require spectacles for near vision.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- High myopia presents unique challenges in cataract surgery.
- Axial lengths of 27 mm and over are considered high myopia.
Purpose of the Study:
- To evaluate outcomes of cataract surgery with and without intraocular lens (IOL) implantation in highly myopic patients.
- To compare postoperative complications and visual acuity between aphakic and pseudophakic groups.
Main Methods:
- Retrospective evaluation of 99 eyes undergoing cataract surgery alone (aphakic group) and 84 eyes with IOL implantation (pseudophakic group).
- IOL power calculated using the SRK formula.
- Postoperative complications, refractive outcomes, and visual acuity were assessed.
Main Results:
- No statistical difference in postoperative complications between aphakic and pseudophakic groups.
- Visual acuity of 20/40 or better achieved by 51% of aphakic and 63% of pseudophakic patients.
- 65% of pseudophakic patients achieved good near visual acuity, with 87% not requiring correction for near vision.
Conclusions:
- Intraocular lens implantation is a viable option for highly myopic patients.
- Most pseudophakic patients achieve satisfactory uncorrected near vision and comfort for daily activities.
