Abstract Details

Purpose:

To assess visual and refractive results of TECNIS® Symfony Extended Range of Vision IOL (ZXR00)) implantation for refractive correction in cataract patients after radial keratotomy (RK).

Setting:

New Mowasat Hospital, Kuwait

Methods:

Twenty five patients were enrolled for bilateral surgery. Patients were implanted with TECNIS Symfony Extended Range of Focus lens in the context of cataract surgery following RK. Patients were ≥48 years of age and had preoperative best-corrected visual acuity ≤20/60 in both eyes, pupil size >3.5 mm, and <1.5 D of corneal astigmatism. IOL power calculation was done using the Haigis formula aiming at postoperative refraction of -1.00. Patients were evaluated preoperatively, operatively, and postoperatively on Day 1, Day 7, Month 1, and Month 3. and included distance, intermediate and near visual acuity (VA), and subjective outcomes.

Results:

Three months postoperatively, binocular results without correction revealed 80% (20/25) of patients had distance VA of 20/30 or better, 92% (23/25) had intermediate VA of 20/30 or better, and 84% (21/25) had near VA of 20/30 or better. At Month 3, the majority of patients reported "none" for visual symptoms of glare, halo, starbursts, or other – blur. All patients had early postoperative hyperopic refraction associated with corneal edema, but at the third month postoperatively 40% of the eyes were within ±0.50 D refraction, whereas 48% were within ±1.00 D.

Conclusions:

Three months postoperatively, the use of the increased depth of focus of the TECNIS Symphony IOL with phacoemulsification for patients previously had radial keratotomy provided excellent uncorrected VA at near, intermediate, and far distances with minimal ocular symptoms
