目的：探讨超声乳化晶状体吸除联合囊袋上经巩膜缝线固定人工晶状体(intraocular lens,IOL)植入术治疗球形晶状体(microspherophakia,MSP)的有效性和安全性。方法：采用回顾性分析，选取2019年1月至 2020年6月期间在复旦大学附属眼耳鼻喉科医院进行治疗的MSP患者37例(37眼)，随机分为两组，纳入行超声乳化晶状体吸除联合囊袋上巩膜缝线固定IOL植入术(supra-capsular and scleral-fixated intraocular lens implantation,SCSF-IOL)的MSP患者20例(20眼)和行超声乳化晶状体吸除联合改良型囊袋张力环植入术(transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation,MCTR-IOL)的MSP患者17例(17眼)，观察两组术后最佳矫正视力及并发症等情况。结果：两组术后最佳矫正视力比术前均有改善(P<0.001)，而组间比较差异无统计学意义(P=0.326)。两组的IOL倾斜度相当(P=0.216)。预防性Nd:YAG激光后囊膜切开术在SCSFIOL术后1周至1个月进行。在SCSF-IOL组，2眼(10.00%)需要重复激光治疗，1眼(5.00%)出现囊口偏心。后囊膜混浊是MCTR组最常见并发症(6眼,35.29%)。随访期间两组均未出现IOL脱位、继发性青光眼和视网膜脱离。结论：SCSF-IOL是治疗球形晶状体的简单易行的手术方式，疗效与MCTR-IOL相当。Nd:YAG激光后囊膜切开术是预防SCSF-IOL术后囊袋并发症的必要手段。
Objective: To investigate the efficacy and safety of phacoemulsification combined with supra-capsular and scleral-fixated intraocular lens (IOL) implantation in the treatment of microspherophakia (MSP). Methods: by retrospective analysis, 37 MSP patients (37 eyes) who were treated in our hospital from January 2019 to June 2020 were randomly divided into two groups, including 20 MSP patients (20 eyes) who treated by SCSF-IOL and 17 MSP patients (17 eyes) who treated by transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation (MCTR-IOL). The best corrected vision and complications were observed. Results: the best corrected vision was significantly improved in both groups (P < 0.001), but there was no remarkable difference between the two groups (P = 0.326). The IOL tilt was also comparable (P = 0.216). Prophylactic Nd: YAG laser posterior capsulotomy was performed from 1 week to 1 month after the SCSF-IOL procedure. In the SCSF-IOL group, two eyes (10.00%) needed repeated laser treatment, and one eye (5.00%) had a decentered capsule opening. Posterior capsular opacification was the most common complication (6, 35.29%) in the MCTR group. No IOL dislocation, secondary glaucoma, or retinal detachment was observed during follow-up. Conclusions: SCSF-IOL is a simple and viable surgical option for managing MSP and is comparable with the MCTR-IOL. Nd: YAG laser posterior capsulotomy is a necessary mean to prevent residual capsule complications after the SCSF-IOL procedure.

Objective: To analyze the application of general anesthesia in the ambulatory glaucoma surgery. Methods: This retrospective study collected 71 patients who underwent ambulatory glaucoma surgery withgeneral anesthesia at Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2023 to June 2023, and 154 patients who underwent similar glaucoma surgery with local anesthesia during the same period. Age differences between the two groups were balanced by propensity score-matched analysis. The main outcome measures were the patient's post-operative discharge time, and the secondary end points included the duration of surgery, the patients' preoperative and postoperative intraocular pressure (IOP), visual acuity status, central anterior chamber depth, peripheral anterior chamber depth, mannitol use, the difference in IOP reduction after surgery compared to preoperative. Results: After propensity score-matched analysis, as compared with group L, general anesthesia did not prolong the patient's post-operative discharge time(P>0.05).Patients in the group G displayed significant higher IOP (P<0.001), shallower central anterior chamber depth (P=0.018), and shallower peripheral anterior depth (P<0.001). The dramatic reductions in IOP after surgery were exhibited in group G as compared with group L(P=0.002). There were no statistically significant differences in postoperative central anterior chamber depth, incidences in postoperative mannitol use, as well as incidences in visual acuity improvement on the first day after surgery. Conclusion: Glaucoma patients with poor preoperative ocular conditions were able to complete the complex glaucoma surgery under general anesthesia without prolonging their post-operative discharge time.

Patients with low vision are severely impaired in visual function due to different ocular and neurological disorders,which have a serious impact on their daily activities (such as reading and driving), quality of life and mental health.People's perception of external information mainly comes from vision. Expect for the life-threatening major diseases,visual damage has the greatest impact on people's senses. With the ageing of the population, the problem is getting worse, and low vision has become a serious public health problem in the world. Currently the development of low vision rehabilitation is facing a huge challenge in clinical and scientific research, to develop a visual impairment assistance technology that can effectively improve visual function while balancing multiple functions. It requires the joint development and cooperation of multiple disciplines such as medicine, biology, engineering, microelectronics, and computer science. Low vision rehabilitation provides patients with appropriate visual impairment assistance technology,maximizing the use of residual vision and visual function of patients, improving the functional limitations associated with low vision, effectively improving their independence and overall quality of life, and makes it possible for them to live, work and integrate into the society independently. This article reviews the progress in the application on visual impaired assistive technologies such as classic visual aids, artificial vision (visual prostheses/visual sensory replacement devices), transcranial stimulation and visual biofeedback training in low vision rehabilitation.
