Objective: To assess the efficacy and safety of phakic refractive lens (PRL) implantation for the correction of ultra-high myopia. Methods: This self-controlled case series study included 39 eyes of 24 patients with ultra-high myopia who underwent PRL implantation at Shenzhen Eye Hospital between January 2018 and September 2020. The study comprised 13 eyes in 8 males and 26 eyes in 16 females, with a mean age of (31.15 ± 6.33) years. Postoperative parameters, including refraction, visual acuity (UCVA, BCVA), intraocular pressure, corneal endothelial cell count,vault, and surgical complication were observed. Results: The median follow-up time was 5.5 (3, 11) months. The refraction significantly decreased from preoperative (-22.29±4.96) D to postoperative (-0.28±1.01) D (t=24.421, P<0.001). Postoperatively, 82.4% of eyes achieved a spherical degree within ±0.5 D, and 91.2% within ±1.0 D. LogMAR UCVA significantly improved from 1.40 (1.30, 1.70) preoperatively to (0.28±0.20) postoperatively. LogMAR BCVA significantly improved from 0.40 (0.22, 0.70) preoperatively to 0.15 (0.00, 0.30) postoperatively (P<0.001 for all). Postoperative BCVA improved by 3.00 (1.00, 5.00) lines compared with preoperative BCVA, with no instances of BCVA loss in any patient. Intraocular pressure values showed significant differences among preoperative, 1 day postoperative and last follow up (F=8.779, P=0.012). Intraocular pressure increased significantly 1 day after surgery compared to before surgery (Z=-3.401, P=0.001), but decreased significantly at the last follow-up compared to 1 day postoperatively(Z=-2.685, P=0.007), with no significant difference in intraocular pressure between preoperative and last follow-up (Z=-0.894, P=0.371). Corneal endothelial cell count decreased significantly from preoperative (2 782.20±296.30)/mm2 to postoperative (2 472.54±394.32)/mm2 (t=?5.437, P<0.001), with a mean loss of 11.2%. The average vault at the last follow-up was (379.00±283.27) μm, of which 0~250 μm in 12 eyes (36.4%), 250~750 μm in 19 eyes (57.6%), and > 750 μm in 2 eyes (6%). In 21 eyes, the vault at 3 months postoperative (269.81±194.67) μm was significantly lower than that at 1 month postoperative (373.62±195.75) μm (t=?2.917, P=0.009). Postoperative complications included steroid-induced glaucoma (2 eyes in 1 case), PRL optical surface crack (1 eye), macular hemorrhage (1 eye), and PRL decentration (3 eyes in 2 cases). Conclusions: PRL implantation is a safe and effective intraocular refractive surgery for ultra-high myopic patients. Nonetheless, it should be neccessary to observe for long-term efficacy and saff lens; high myopia

Methods: The clinical data of 46 patients with bilateral retinoblastoma who received intravenous chemotherapy combined with transpupillary thermotherapy (TTT) or enucleation from December 2008 to December 2019 in our department were analyzed retrospectively. The eye salvage rate, enucleation rate, visual acuity, and chemotherapy side effects were evaluated. Results: The 46 enrolled patients were 27 males and 19 females, at an average age of (13.21±11.13) months at the first visit. Among them, 10 received chemotherapy, 11 received chemotherapy combined with TTT, 17 received chemotherapy combined with TTT and enucleation,and 2 received chemotherapy combined with freezing, 6 received chemotherapy combined with freezing and enucleation. After treatment, 58 eyes were salvaged, with a total salvage rate of 73.1% (57/78), and the eyes that preserved vision account for 64.1% (50/78). The eye salvage rate in each stage were 100.0% for stage A and B, 86.7% for stage C, and 94.1% for stage D, 35.7% for stage E. Twenty-four eyes were enucleated, with a total enucleation rate of 26.1% (24/92), and among 35 eyes at stage E, 21 eyes were enucleated, accounting for 60.0%(21/35). The average time of chemotherapy was 4.1±1.9 and the myelosuppressive effects of chemotherapy include leucopenia, thrombocytopenia and hemoglobinopenia. During the mean follow-up time of (35.4±23.8) months, 7 (15.2%) patients died, and 39 (84.8%) cases survived. The 5-year cumulative survival rate was 80.2%. Conclusion: Intravenous chemotherapy combined with local treatment has a good overall effect and plays an important role in the treatment of bilateral retinoblastoma. Intravenous chemotherapy leads to myelosuppression, and the myelosuppression gradually recovered after stopping intravenous chemotherapy.
目的：探究球面塑形镜、环曲面塑形镜在矫治近视复合散光的有效性及安全性。方法：回顾分析宜昌市第一人民医院2016年3月至2018年3月角膜塑形镜治疗青少年近视94例(178眼)，按佩戴塑形镜类型分为球面塑形镜组(48例，90眼)与环曲面塑形镜组(46例，88眼)。记录配镜前、佩戴1年后、停戴1周后的视力、角膜散光、眼轴长、球镜屈光度、眼压、泪膜破裂时间及角膜着染率。结果：戴镜1年后，2组组内相比，散光、球镜度数、眼压、泪膜破裂时间均降低，但2组组间相比，仅散光度数差异有统计学意义(P<0.01)。戴镜1年后，两组视力较戴镜前显著提高，停戴后近视度数较佩戴前增加，但组间差异无统计学意义(P>0.05)；2种塑形镜角膜着染发生率差异无统计学意义(P>0.05)。结论：2种塑形镜均能够降低近视复合散光患者度数，有效提高患者视力，但并不能完全阻止近视的进展。虽然环曲面塑形镜在矫正散光方面有优势，但总有效性与安全性并不占优势。
Objective: To observe the effectiveness and safety of orthokeratology lens and toric design othokeratology treatment for compound myopic astigmatism. Methods: From March 2016 to March 2018, 94 teenagers(178 eyes) were selected as the subjects of study. They were divided into two groups according to the type of orthokeratology: the orthokeratology lens group (48 cases, 90 eyes) and the toric design othokeratology group(46 cases, 88 eyes). Visual acuity, corneal astigmatism, axial length, spherical lens refraction, intraocular pressure,tear film rupture time and corneal staining rate were recorded before, after 1 year and after 1 week. Results: After 1 year of wearing the lens, astigmatism, spherical lens degree, intraocular pressure and tear film rupture time were all decreased in the 2 groups compared with each other, but only astigmatism degree was statistically significant between the 2 groups compared with each other (P<0.01). After wearing the glasses for 1 year, the visual acuity of the two groups was significantly improved compared with that before wearing the glasses, and the myopia degree was increased after stopping wearing the glasses compared with that before wearing the glasses, but the difference between the two groups was not statistically significant (P>0.05). There was no statistical significance in the incidence of corneal staining between the two types of shaping lenses (P>0.05). Conclusion: Both of the two shaping lenses can reduce the degree of myopic patients with complex astigmatism and effectively improve the visual acuity of patients, but they can not completely prevent the progress of myopia. Although toroidal shaping mirror has advantages in correcting astigmatism, its overall effectiveness and safety are not.
