Abstract

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.
