Pinhole Optics Meet Cataract Surgery

Small-aperture IOL shows promise for cataract patients with pre-existing corneal comorbidities

1

A study evaluated the IC-8 pinhole intraocular lens (IOL) in 67 eyes of 45 patients with cataract and significant corneal comorbidities.
2

The IC-8 lens features a 1.36 mm central aperture designed to improve retinal image quality by reducing optical aberrations.
3

Mean corrected distance visual acuity improved from 0.56 logMAR preoperatively to 0.16 logMAR post-surgery in eyes receiving the IC-8 lens alone.
4

Among keratoconic eyes, nearly 70% achieved uncorrected visual acuity of 6/9 or better after implantation of the IC-8 lens.
5

No significant differences were found in refractive prediction accuracy among five contemporary IOL power calculation formulas used in the study.
