Purpose: To compare the refractive outcomes of closed C-loop and C-loop intraocular lenses (IOLs) following phacovitrectomy with gas tamponade.
Methods: Medical records of 42 patients (43 eyes) who underwent phacovitrectomy with gas tamponade for idiopathic macular holes between January 2021 and June 2022 were retrospectively reviewed. Closed C-loop (26 eyes; Eyelike K-flex Aspheric®, Koryo Eyetech, Seoul, Korea) and C-loop (17 eyes; Tecnis® ZCB00, Johnson & Johnson Vision, Santa Ana, CA, USA) IOLs were surgically implanted. The main outcome measures were postoperative prediction error and absolute error.
Results: There was no significant difference in mean absolute error at 5 months postoperatively (0.34 ± 0.24 diopters [D] and 0.30 ± 0.25 D in the closed C-loop and C-loop IOL groups, respectively; p = 0.502). The mean prediction error at 5 months postoperatively also showed no significant difference between the groups (-0.28 ± 0.30 D and -0.16 ± 0.36 D, respectively; p = 0.242). Myopic shift was observed in both groups.
Conclusions: There was no significant difference in refractive outcomes between closed C-loop IOLs and C-loop IOLs. A myopic shift was observed in both groups; this should be taken into consideration when calculating IOL power following phacovitrectomy with gas tamponade.
