PURPOSE: To determine the difference between the attempted and the achieved postoperative refractive error after sutureless intrascleral fixation of the haptics of an implanted intraocular lens (IOL).
PATIENTS AND METHODS: This was a retrospective study of the medical charts of patients who had undergone sutureless intrascleral fixation of an IOL. The IOLs were fixed by inserting the haptics into scleral tunnels with or without flanges. The differences between the attempted and achieved postoperative refractive error (spherical equivalent) were determined. The relationships between the surgical options and the differences of the refractive error and degree of astigmatism were also determined.
RESULTS: Two hundred and twenty-three eyes were studied. There was a myopic shift of - 0.38 ± 1.13 diopters (D). The mean of the differences between the achieved postoperative and the attempted refractive error was 0.89 ± 0.79 D. The achieved refractive error was significantly correlated with the attempted refractive error (P < 0.001, R2 = 0.631). The surgical procedures selected were not significantly associated with the differences between the attempted and achieved refractive error. The size of sclerocorneal incision and presence of sutures were significantly associated with the final degree of astigmatism (P = 0.006 and 0.008, respectively).
CONCLUSIONS: The postoperative refractive error was significantly correlated with the attempted refractive error after intrascleral fixation of an IOL. The wound construction was associated with the postoperative degree of astigmatism.
