Iris-Claw IOL Through a Scleral Tunnel Incision Assessed
Implanting an iris-claw intraocular lens (IOL) in the retropupillary position through a scleral tunnel incision is an effective alternative to aphakia without capsule support, according to a retrospective case series involving 76 eyes of 75 individuals.
Participants received an iris-claw IOL from a single surgeon between 2011 and 2017 via either scleral tunnel or corneal incision. Investigators looked at outcome by incision type and lens position. Among the results:
- Postop uncorrected and corrected distance visual acuities were significantly improved in all patients.
- Average uncorrected distance acuity was significantly better in patients receiving scleral tunnel vs corneal incision.
- Patients in the scleral tunnel incision group had lower surgically induced astigmatism (0.73 vs 2.49 diopters).
- No differences were seen by incision type.
