Abstract Details

Purpose:

To evaluate visual and refractive outcomes and rotational stability of toric intraocular lens (IOLs) implantation in eyes with previous ocular surgeries.

Setting:

An academic tertiary eye-care center.

Methods:

This study included 59 eyes (48 patients) with a history of corneal, vitreoretinal and/or glaucoma surgery whose cataract was treated with toric IOL implantation. Patients ≥18 years old, with a history of previous ocular surgery, and a preoperative corneal astigmatism >0.75 diopters (D), were included. Outcomes were recorded at 3 postoperative follow-up intervals: short-term (~1 month), mid-term (~3-12 months), and long-term (>12 months to 4.5 years).

Results:

Achieved spherical equivalent (SEQ) was within ±1.0 D of target SEQ in 93.5%, 88.4%, and 86.2% of the cases at the short-term, mid-term, and long-term follow-up intervals, respectively. Best corrected visual acuity (BCVA) was 20/40 or better in 88.9%, 92.7%, and 96.0% of cases during the short-term, mid-term, and long-term follow-up intervals, respectively. Of the examined eyes, 93.9% and 88.4% had IOL axes within 5˚ of intended axis at postoperative month 1 and months 3-12, respectively. Refractive prediction errors, UCVA, BCVA, and IOL rotation were not significantly different between corneal and vitreoretinal surgery groups.

Conclusions:

Toric IOLs provided a significant and sustained improvement in visual acuity and refraction in eyes with history of prior ophthalmic surgery, with similar outcomes achieved in corneal and vitreoretinal surgery groups.
