Purpose: To evaluate the difference between the predicted postoperative refraction and the actual postoperative refraction after simultaneous vitrectomy and cataract surgery with sulcus fixation of an intraocular lens (IOL).
Methods: The records of patients with simultaneous vitrectomy and cataract surgery with sulcus IOL implantation (group 1) and with in-the-bag IOL implantation (group 2) were reviewed. We compared the spread between the predicted and actual refractive errors in the two groups.
Results: Group 1 consisted of 19 eyes in 19 patients and group 2 consisted of 23 eyes in 20 patients. The spread between the predicted and actual refraction (spread = actual-predicted) was -0.71 ± 1.02 D in group 1 (p = 0.012) and -0.07 ± 0.74 D in the group 2 (p = 0.86). The actual refractive errors in group 1 shifted toward myopia from the predicted in-the-bag refraction when compared with group 2.
Conclusions: For the implantation of an IOL in the sulcus after simultaneous vitrectomy and cataract surgery, the IOL power should be approximately 1.0 D less than the power for in-the-bag fixation.
