Abstract	Background To investigate the effect of surgical steps optimization in pars plana vitrectomy (PPV) with internal limiting membrane (ILM) flap for macular hole retinal detachment (MHRD) in pathological myopia. Methods A retrospective, consecutive, nonrandomized comparative study. High myopic eyes diagnosed with MHRD receiving PPV with ILM flap from March 2019 to June 2020 in Department of Ophthalmology, Xiangya Hospital, Central South University were included in the study. Patients were included into two groups based on different design of surgical steps. In the routine group, extension of posterior vitreous detachment (PVD) towards periphery was performed right after induction of PVD. In the experiment group, the retina was reattached with drainage of subretinal fluid through macular hole before peripheral vitreous was dealt with. Complete ophthalmic examinations were performed before and after surgery. The follow-up time was at least 6 months. The rate of iatrogenic retinal break and length of operation were compared between the two groups. Results Thirty-one eyes from 31 patients were included in the study with 15 in the experiment group and 16 in the routine group. Demographics showed no statistically significant difference between the two groups. Post-op BCVA, rate of macular hole closure and rate of retinal reattachment were similar in the two groups. The rate of iatrogenic retinal break in the experiment group was significantly lower than that in the routine group (6.7% vs. 37.5%, P < 0.05). The average length of operation was 78.6 ± 18.8 min in the routine group and 64.0 ± 12.1 min in the experiment group (P < 0.05). Conclusions Optimized design of surgical steps in PPV for MHRD could effectively decrease the rate of iatrogenic retinal tear and shorten the length of operation.
