Uncorrected and corrected distance visual acuity (UDVA and CDVA) and postoperative complications were ADULT CHEWABLE- CRANB / RASP evaluated until postoperative months 24.The refractive outcomes and the surgically induced astigmatism (SIA) vector were compared between groups.Results: The medical records of 107 eyes from 107 patients with mean age of 65.31 ± 12.15 years were reviewed.
Eyes with a frown incision showed the best UDVA, followed by those with L-shaped and conventional incisions (P = 0.003).Eyes with an L-shaped incision or frown incision had a lower SIA than that of the conventional incision group at postoperative 6 months (mean ± standard deviation [SD] SIA, 0.86 ± 0.85 D, 0.
63 ± 0.37 D, and 1.70 ± 1.27 D for frown incision, L-shaped incision, and conventional incisions, respectively; P = 0.004).
Conclusion: The frown incision and Fridge Compressor Module L-shaped incision induced a significantly smaller SIA than the conventional incisions, which was associated with better UDVA postoperatively.Keywords: aphakia, astigmatism, intraocular lens dislocation, retropupillary iris-claw intraocular lens, scleral tunnel incision, sclerocorneal incision.
