AIM: To examine the refractive prediction error in high myopic eyes after ***: This retrospective comparative case series included 91 eyes(18 high myopic eyes and 73 non-high myopic eyes) of 91 patients who underwent successful phacovitrectomy(phacoemulsification, intraocular lens implantation, and pars plana vitrectomy). The high myopic eyes were defined as the eye with more than 26.0mm of axial length. The postoperative prediction error of mean error and mean absolute error were evaluated at4 mo postoperatively. Axial length and keratometry measurement were performed preoperatively and 4mo postoperatively using the IOL ***: The refractive outcome after phacovitrectomy showed significantly greater myopic shift in the high myopic eyes [-1.08 ±0.87 diopters(D)] than that in the non-high myopic eyes(-0.43 ±0.63 D, P =0.004). Axial length and keratometric value in the high myopic eyes were significantly increased(P =0.043, 0.037 respectively),whereas those in the non-high myopic group were not significantly increased(P =0.135, 0.347 respectively). The change of the axial length in the myopic eye(0.46±0.28 mm)was greater than that in the non- high myopic eye(0.11 ± 0.34 mm; P <0.001).CONCLUSION: High myopic eyes showed more myopic shift than non-high myopic eyes after *** cause of myopic shift in high myopic eyes seems tobe attributed to actual elongation of the axial length in high myopia.

Refractive Outcomes Using the Lenstar Optical Low Coherence Reflectometry Biometer in phacovitrectomy for Epiretrinal Membranes and Macular Holes

引用

Open Journal of Ophthalmology 2017年第3期7卷 216-224页

作者： Mark A. P. Fajgenbaum Julian Robins Tom H. Williamson Ophthalmology Department St. Thomas’ Hospital London UK

Objective: To compare refractive outcomes using the Lenstar optical low-coherence reflectometry (OLCR) biometer in the following cases: phacovitrectomy for epiretinal membranes and macular holes (phacovitrectomy group);sequential cataract surgery after prior vitrectomy (sequential-phaco group);routine cataract surgery (phaco-only group). Methods: This study was a retrospective, consecutive comparative series. Main outcomes were mean prediction error (ME) and mean absolute prediction error (MAE). Secondary out-come was the variance in prediction error. Results: ME was significantly more myopic in the phacovitrectomy group (-0.08 ± 0.77D, mean ± SD, p = 0.04) and the sequentialphaco group (-0.09 ± 0.51D, p = 0.01) compared to the phaco-only group (+0.24 ± 0.53D). MAEs were not statistically different across the 3 groups. The phacovitrectomy group had a wider variance in prediction errors compared to the phaco-only group (p = 0.03). Conclusions: There is a myopic shift of approximately -0.3D in both phacovitrectomy and sequential-phaco cases compared to phaco-only cases when using OLCR-based optical biometry. phacovitrectomy outcomes are more variable compared to phaco-only eyes.
