Background: Different visual acuity chart can be targeted to evaluate the visual function of patients with different eye diseases. We conducted a comparative analysis of the digital logarithm of the minimum angle of resolution (LogMAR) vision chart and the standard logarithmic vision chart for the measurement of visual acuity after retinal detachment surgery.

Methods: We used the digital LogMAR vision chart and the standard logarithmic vision chart to measure the visual acuity of 100 patients (100 eyes) who underwent retinal detachment surgery at our hospital using the LogMAR recording method and compared the differences between the mean measurements obtained by both methods for all patients and for different age groups.

Results: When all of the patients were analyzed, the mean visual acuity differed between the digital LogMAR vision chart and the standard logarithmic vision chart by –0.07 LogMAR units. No significant difference was observed in the mean visual acuity between the two vision charts in the 10-20 year and 21-40 year age groups (P>0.05), while a significant difference was observed in post-operative mean visual acuity between the two vision charts for patients aged 41-65 years (P<0.05).

Conclusions: Both the digital LogMAR vision chart and the standard vision chart were effective and reliable for the measurement of visual acuity. The visual acuity measured by the standard vision chart was higher than that measured by the digital LogMAR vision chart. We recommend using the digital LogMAR vision chart as the preferred chart for measuring visual acuity after retinal detachment surgery.

Background: To investigate early change of corneal aberrations after 2.8-mm superior incision phacoemulsification.

Methods: This study comprised 80 eyes of 75 patients. All the patients underwent phacoemulsification with monofocal foldable intraocular lens (IOLs) implanted through a 2.8-mm superior corneal incision. The anterior corneal wavefront aberrations for the 6.0-mm pupillary diameter was measured by iTrace wavefront aberrometer (Tracey Technologies, Inc.) preoperatively and 1 month postoperatively. Changes of root mean square (RMS) values of Z(3, -3), Z(3, 3), Z(3, -1), Z(3, 1), and Z(4, 0) and total high order aberration (HOA) were evaluated.

Results: The uncorrected and corrected visual acuities improve significantly (P<0.001). No significant postoperative changes were observed in spherical aberration (P=0.652). Significant changes in vertical coma and vertical trefoil (0.005±0.214 vs. -0.049±0.242, P=0.037; -0.141±0.222 vs. -0.258±0.359, P=0.001; separately). However, the total HOAs increased after cataract surgery (0.567±0.161 vs. 0.688±0.343, P<0.001).

Conclusions: Corneal vertical coma and vertical trefoil changes significantly in 2.8 mm superior corneal incision phacoemulsification cataract surgery. In addition, those had a trend to negative direction.

目的：探讨白内障小切口非超声乳化术向超声乳化术转型中的技术转变。

方法：对 2009 年 4 月 - 2009 年 12 月“光明工程”中白内障超声乳化手术转型期 193 例 193 眼的情况进行回顾性分析，同期行小切口非超声乳化吸除术患者 43 例 48 眼作对照。

结果：对照组术后第 1 日裸眼视力大于或等于 0.5 的比例高于治疗组（P < 0.05），术后第 1 周、 第 1 个月裸眼视力大于或等于 0.5 及术后第 1 个月最佳矫正视力大于或等于 0.5 的比例，两组比较差异无统计学意义（均 P > 0.05）。对照组术后主要并发症比率均低于治疗组（均 P < 0.05）。

结论：小切口非超声乳化术向超声乳化术转型中，由于技术差异较大，发生后囊破裂和角膜内皮水肿的几率较高，转型此手术要有熟练的显微手术基础、处理并发症的能力和一定的设备条件。

Purpose: To investigate the clinical outcome during the conversion from small incision sutureless cataract surgery (SICS) to phacoemulsification cataract surgery (phaco).

Methods: During the conversion period from SICS to phaco, 241 cataract cases were assigned to SICS and phaco surgery procedures. The intraoperative complications and early postoperative outcomes were assessed.

Results: The 1st day visual acuity outcome (VA 0.5 or better) was lower in the phaco group (P < 0.05); however, the visual acuity outcomes were no longer statistically different at 1 week and 1 month visits (P > 0.05 for each visit). Among 193 cases operated in the phaco group, 51 cases (26.4%) developed corneal edema at the 1 day visit, 13 cases (6.7%) had posterior capsular rupture, 5 cases (2.6%) had zonular rupture, and 5 cases (2.6%) failed to implant IOL. These rates were higher than those found in the SICS group.

Conclusion: The outcome of phaco cataract surgery is comparable with SICS during this conversion period. Techniques that the surgeons may pay attention to are also discussed.

目的：评价药物治疗无效的开角型青光眼及部分复杂性青光眼行二氧化碳激光辅助下外层Schlemm管消融术(CO2 laser-assisted sclerectomy surgery，CLASS)的短期临床安全性及有效性。方法：收集2015年5月至2016年1月解放军总医院眼科行CLASS手术和小梁切除手术的青光眼患者各23例，共46例46只眼。观察术后1周、1个月和3个月眼压及并发症发生情况。结果：两组术后1周、1个月及3个月眼压较术前均明显下降(P=0.000)。术后1周、1个月及3个月时CLASS手术组眼压平均值均低于小梁切除术组，但无统计学差异(P>0.05)。CLASS手术组23例均无浅前房、脉络膜脱离等并发症出现。小梁切除手术组有4例在术后早期出现浅前房，其中1例出现脉络膜脱离，经治疗后均治愈。结论：CLASS手术在有效降低眼压的同时，能大幅降低患者术后出现浅前房等并发症的概率，但其远期降眼压效果及并发症发生情况有待进一步深入研究。

Objective: To evaluate the short-term of clinical safety and efficiency of CO2 laser-assisted sclerectomy surgery (CLASS) in patient with open-angle glaucoma and complicated glaucoma. Methods: Our study involved 46 eyes of 46 patients with glaucoma that underwent CLASS and trabeculectomy respectively by the same surgeon (Zhaohui Li) from May 2015 to January 2016 at the PLA General Hospital. Intraocular pressure and complications 1 week, 1 month and 3 months after operation was observed separately. Results: The intraocular pressure (IOP) 1 week, 1 month and 3 months after surgery decreased obviously (P=0.000). Compared to the trabeculectomy group 1 week, 1 month and 3 months after surgery, IOP of CLASS group was lower. But there was no statistically significant difference between these two groups (P>0.05). There was no complication occurred in CLASS group. Early postoperative complications occurred in trabeculectomy group included shallow anterior chamber and choroidal detachment, and they were all successfully resolved by pharmacotherapy. Conclusion: CLASS operation could reduce intraocular pressure effectively and decrease the incidence of complications, such as postoperative shallow anterior chamber in patients with glaucoma. However, its long-term effect and complications need to be further studied.

目的：探讨复合小梁切除术后并发浅前房的原因、治疗和预后情况。

方法：对在该院行复合小梁切除术的 267 例（302 眼）青光眼患者进行回顾性研究 ，观察术后浅前房的发生原因、治疗、预后情 况。

结果：302 眼中有 43 眼出现浅前房（1424％）。 术后滤过过强、滤过口渗漏，脉络膜脱离及睫状环阻滞是浅前房的主要原因，浅前房发生后给予保守或手术治疗，43 眼前房均恢复正常。

结论：复合小梁切除术后浅前房是常见的一种并发症。术中控制滤过率，合理应用丝裂霉素可减少浅前房的发生；术后密切观测前房、眼压和滤过情况，及早对浅前房进行干预可明显改善预后。

Purpose: To investigate the clinical cause, therapy and prognosis of shallow anterior chamber after complex trabeculectomy surgery of glaucoma.

Methods: A retrospective study of 267 patients (302 eyes) diagnosed with glaucoma at our hospital was reviewed.

Result: Forty-three among 302 eyes presented shallow anterior chamber (14.24%). The main causes of shallow anterior chamber after surgery included excessive filtering function, conjunctival exudation, choroidal detachment and ciliary circle block. These patients recovered after receiving conservative or surgical treatment.

Conclusions: The shallow anterior chamber is a frequent complication occurring following complex trabeculectomy surgery. The occurrence of this complication may be decreased by controlling filterableness and moderately applying mitomycin C intraoperatively; the prognosis may be significantly enhanced by detecting main measurements including anterior chamber, intraocular tension, filtration condition, and by interfering in shallow anterior chamber early after complex trabeculectomy surgery.

A 74-year-old man presented with a three-year history of foreign body sensation in the right eye after cataract surgery. He underwent uneventful trabeculectomy with mitomycin C (MMC) in the right eye seven years ago. Slit-lamp examination revealed a large avascular filltration bleb overhanging on the cornea with a thin base connected to the conjunctiva. Preoperative ultrasound biomicroscopy (UBM) impressions were confirmed by leakage of aqueous from the incision intraoperatively. Surgical dissection and revision of the bleb was performed with satisfactory outcome. Histopathologic evaluation showed proliferation of fibrous tissue under the conjunctival epithelia with irregular cystoids change. The current case may be the first report of a post-trabeculectomy overhanging filtration bleb related to cataract surgery. The possible mechanism may be related to microleakage of the surgical wound after phacoemulsiff cation which initiated the healing and scarring process.
