Key takeaways:
- Refractive outcomes after cataract surgery may be worse in eyes that underwent scleral buckling.
- Surgeons should warn patients about possible worse outcomes.
NEW ORLEANS — Refractive outcomes after cataract surgery may be worse for patients with a history of scleral buckling despite advancements in technology, according to a poster here.
“While the advent of more advanced biometry devices and IOL power calculation formulas has improved outcomes, these eyes may still experience poor refractive outcomes with a larger variability in the postop refractive outcomes,” Rucha K. Borkhetaria told Healio/OSN at the Association for Research in Vision and Ophthalmology meeting.
The single-center retrospective consecutive case series included 40 eyes with a history of scleral buckling for retinal detachment that later underwent cataract surgery.
The Barrett Universal II formula was used to calculate predicted postoperative spherical equivalents, mean prediction error and absolute prediction error for the implanted IOLs.
The mean prediction error was –0.05 ± 0.68 D, and the absolute prediction error was 0.49 ± 0.48 D.
While the mean prediction error was close to zero in eyes that underwent scleral buckling, variability was much higher than what would be expected in eyes that did not undergo scleral buckling, Borkhetaria said.
“I think ophthalmologists should be aware and tell their patients who have a previous scleral buckle that come to them for cataract surgery, they may not have the same visual outcome after cataract surgery as patients who don’t have a scleral buckle,” she said.
