Objective: To investigate the predictive accuracy andeffect of capsular tension ring (CTR) implantation with fivenew generation intraocular lens (IOL) calculation formulas [Barrett Universal Ⅱ (BU Ⅱ ), Emmetropia VerifyingOptical (EVO), Kane, Pearl-DGS and Hill-RBF 2.0] in high myopia patients. Methods: This is a prospectivecase-control study. The patients were enrolled with an axial length (AL)≥27.00 mm, and underwent cataract surgery with AR40E IOL implantation at the Shaanxi Eye Hospital from December 2020 to September 2021. Thepatients were randomly assigned to the CTR implantation group (group A) and the non-CTR implantation group(group B). With the ocular parameters measured by the IOL-Master 700, the IOL power was calculated with theBU Ⅱ formula before surgery. The postoperative actual equivalent spherical diopter (SE) were recorded,and the predicted error (PE) and absolute error (AE) using the five formulas were recorded and compared at 1 week, 1 month, and 3 months, repsectively. Group A was divided to A1 (27.00 mm ≤ AL ≤ 30.00 mm) and A2 (AL>30.00 mm), and group B was divided to B1 (27.00 mm ≤ AL ≤ 30.00 mm) and B2 (AL>30.00 mm). The effects of CTR implantation and the accuracy of the formulaswere analyzed with different AL ranges. Results: A total of 63 patients (89 eyes) were included, aged (55.93±10.17) years old, with preoperative AL (30.30± 2.18) mm. There was no statistically significant difference in SE between groups A, A1, and A2 (P>0.05) at different postoperative times. While there was a statistically significant difference in SE between groups B, B1, and B2 (P < 0.05) at 1 week and 1 month after surgery, and between 1 week and 3 months after surgery. There was no statistically significant difference between 1 month and 3 months after suergery (P>0.05). There was no significant difference in the AE using the five formulas among groups A, B, A1, A2, B1, and B2 (H= 9.27, P= 0.06, H= 7.09, P= 0.13, H= 2.44, P= 0.66,H= 8.56, P= 0.07, H= 4.16, P= 0.39, H= 8.72, P= 0.07). There was no statistically significant difference in prediction error changes among the five formulas after CTR implantation (P>0.05). Conclusion: For cataract patients with AL ≥27.00 mm, the refractionvalue in the CTR implantation group tended to stabilizeafter one week of surgery. While in the non-CTR implantation group, the refractionvalue tended to stabilize after one month. CTR implantation had no effect on the accuracy and selection of the five formula, and the five IOL calculation formulas can be normally selected.

青光眼是全球第二大致盲眼病，第一大不可逆性致盲眼病，其中原发性闭角型青光眼(primary angle closure glaucoma，PACG)占25%。激光周边虹膜切除术(laser peripheral iridotomy，LPI)已成为PACG和原发性房角关闭的一线治疗。LPI机制为利用激光在周边虹膜上打孔，解除PACG的瞳孔阻滞，加深前房，扩大房角，恢复生理性房水排出途径，从而降低眼压。研究表明LPI在原发性房角关闭各个疾病进程中均能比较好的控制眼压，是相对安全的治疗方法。
Glaucoma is the second leading cause of blindness and the most common cause of irreversible blindness worldwide. Primary angle closure glaucoma (PACG) accounts for 25% of glaucoma. Laser peripheral iridotomy(LPI) has become the first line treatment for PACG and primary angle closure (PAC). The mechanism of LPI is to use laser to create a hole in peripheral iris to relieve pupil block, deepen anterior chamber, expand chamber angle,restore pathway of physiological aqueous discharge and reduce intraocular pressure. Studies have shown that LPI can control intraocular pressure well in all stages of PAC, which is safe for PAC.
原发性干燥综合征(primary Sj?gren’s syndrome，SS)是一种主要累及外分泌腺体的自身免疫性疾病，患者通常因为严重的干眼症状首先就诊于眼科，大多数临床医师对原发性干燥综合征相关性干眼(Sj?gren’s syndrome dry eye disease，SS-DED)认识不足，可能导致漏诊和误诊。侵入性极小的客观检查及生物标志物的发展，将有助于发现SS-DED的真面目，并可能从新的角度阐释其发病机制，为其诊断、分类及治疗提供新的思路。SS-DED的治疗没有特效的药物，大多数患者需接受多种方法的治疗，以了解哪些方法最有效。
Primary Sj?gren’s syndrome is an autoimmune disease that mainly affects exocrine glands. Patients usually refer to ophthalmologists because of severe dry eye symptoms. Most clinicians have insufficient knowledge with dry eye disease associated with primary Sj?gren’s syndrome probably leading to misdiagnosis or missing the diagnosis.The diagnosis of Sj?gren’s syndrome dry eye disease (SS-DED) is difficult, but the extremely invasive objective examination and the development of biomarkers will help to understand this disease and explain its pathogenesis from a new perspective. There is no specific treatment for the SS-DED, and most patients should receive multiple treatments to select the optimal treatment.

Objective: To explore the ocular surface recovery after surgical treatment of strabismus patients. Methods: A total of 92 patients (126 eyes) with strabismus who underwent surgery in our hospital from January 2015 to June 2018 were enrolled. The patients were divided into three groups according to the surgical incision, 42 patients (52 eyes)underwent limbal incision were in group A, 17 patients (19 eyes) underwent trans-muscle end-point incision in group B, and 33 patients (55 eyes) underwent proximal hernia incision in group C. According to the number of muscles involved in the operation, the sick eyes of patients were divided into three groups. The 29 eyes with a single extraocular muscle were a single muscle group, the 42 eyes with 2 extraocular muscles were a double muscle group, and the 21-eye treated with 3 extraocular muscles were a three-muscle group. The ocular surface health recovery time of patients with different incision types and muscle involvement were compared. Results: The first tear film rupture recovery time and tear river height time between group A, B, and C were significantly different,and the data were statistically significant (P<0.05); the first tear film rupture recovery time (14.33±3.26) d and tear river height time (14.54±1.58) d in group A were significantly lower than those in group B and C. The data were statistically significant (F=4.876, P=0.032; F=4.612, P=0.036). The first tear film rupture recovery time and tear river height time between the single, double and three muscle groups were significantly different, and the data were statistically significant (P<0.05); the first tear film rupture recovery time (13.42±3.57) d and tear river height time (8.65±1.62) d were significantly lower in the single muscle group than in the double muscle group and the third muscle group. The data were statistically significant (F=4.975, P=0.028; F=5.024, P=0.025). Conclusion:The number of muscles involved in the operation and the type of surgical incision have an important impact on the health of the ocular surface after surgery. The proximal ankle incision and less number of muscles involved would improve the postoperative recovery of eye health.

Objective: To observe the efficacy of trehalose eye drops on experimental dry eye rat with removal of inside and outside lacrimal glands. Methods: A total of 30 SD rats were randomly divided into a normal group, a control group, and an experimental group, with 10 rats for each group (20 eyes). The normal group was not treated, and the experimental group and the control group were made into a dry eye animal model by removing the main lacrimal gland of the rat. The control group and the experimental group were given with normal saline and trehalose eye drops once a week after the completion of modeling, 4 times a day for 4 weeks. Shirmer I test and fluorescence staining test were carded before and 1, 2, 3, and 5 weeks after modeling. After 5 weeks of modeling, the rats were sacrificed and the expression of Bcl-2 and Bax apoptosis protein in conjunctival epithelial cells was detected by immunohistochemistry in order to observe the relationship between apoptosis of conjunctival epithelial cells and dry eye lesions and tissue damage in dry eye animal models. Results: Schirme I test results showed that there was no significant difference between the control group and the experimental group (P>0.05) except for the 5th week after operation (P<0.05). There was a statistical difference between the two groups and the normal group at each time point after surgery (P<0.05). At the first week after modeling, the corneal fluorescence staining scores of the control group and the experimental group were significantly higher than those of the normal group. After the second week after surgery, there was no significant difference between the control group and the experimental group (P>0.05). The prolongation of time, the 3 week and the 5th week after surgery, the difference between the two groups was statistically significant (P<0.05), and the score of the experimental group was smaller than the control group. The immunohistochemical results of conjunctival epithelial cells showed that the number of Bax protein positive cells in the normal conjunctival epithelial cells was less than that in the control group and the experimental group. The difference between the normal group and the control group was statistically significant(P<0.05). There was no significant difference between the two groups (P>0.05). There was a large amount of Bcl- 2 protein in the normal group, which was more than the experimental group. The difference was not statistically significant (P>0.05), which was more than the control group. The difference was statistically significant (P<0.05); a large amount of Bax protein was positively expressed in the cytoplasm and brownish-yellow particles in the conjunctival epithelial cells of the control group. The positive expression of Bax protein in the experimental group was significantly less than that in the control group, and the difference was statistically significant (P<0.05). A large amount of Bcl-2 protein was positively expressed in the conjunctival epithelial cells of the experimental group, and the expression of Bcl-2 protein in the control group was significantly decreased compared with the experimental group (P<0.05).Conclusion: Trehalose eye drops can reduce epithelial detachment of the cornea and have a protective effect on conjunctival epithelial cells, which can antagonize the apoptosis of conjunctival epithelial cells,thereby enhancing the keratoconjunctival barrier function and improving the ocular surface epithelium caused by dryness. The potential clinical application of trehalose solution for ocular surface epithelial diseases and provide treatment options for ocular surface diseases, such as dry eye.
