Cataract surgery patients who underwent implantation of monofocal IOLs in combination with a small aperture corneal inlay in the nondominant eye experienced improved intermediate and near visual acuity compared with patients who underwent conventional cataract surgery.
The prospective, randomized clinical trial included 16 patients with advanced cataracts who underwent surgery on both eyes in separate surgeries. Eight patients received monofocal IOLs along with a small aperture corneal inlay in the nondominant eye, and eight patients served as controls and received monofocal IOLs in both eyes. Patients were evaluated at 1, 4 and 12 weeks after surgery.
There was no statistically significant difference in mean uncorrected distance visual acuity at 4 and 12 weeks postoperatively between the two groups.
Mean uncorrected intermediate visual acuity was 0.21 logMAR at 4 weeks and 0.20 logMAR at 12 weeks postoperatively in the control group compared with 0.07 logMAR and 0.06 logMAR, respectively, in the inlay group. The inlay group had statistically significantly better uncorrected intermediate visual acuity (P = .03).
Mean uncorrected near visual acuity was 0.35 logMAR at 4 weeks and 0.32 logMAR at 12 weeks postoperatively in the control group compared with 0.11 logMAR and 0.11 logMAR, respectively, in the inlay group. Postoperative uncorrected near visual acuity was better in the inlay group, but the difference was not statistically significant.
“In comparison to IOL-based presbyopia-correcting solutions, the small aperture corneal inlay can be removed without an intraocular procedure in cases where an uninterrupted view of the retina is needed,” the study authors said. “The implantation of small aperture corneal inlays seems to be an interesting alternative for pseudophakic patients who desire good near, intermediate and distance visual acuity with spectacle independence.” – by Robert Linnehan
