不同切口超声乳化白内障摘除术治疗对老年白内障患者眼压、视力的影响

Effect of Phacoemulsification with Different Incisions on Intraocular Pressure and Vision of Elderly Cataract Patients

目的研究不同切口超声乳化白内障摘除术治疗对老年白内障患者眼压、视力的影响。方法选取沈阳市第四人民医院收治的82例高龄白内障患者为研究对象,时间为2019年4月至2020年1月,根据患者的意愿为研究组(n=41,实施角巩膜缘切口超声乳化摘除术治疗)与对照组(n=41,实施角膜切口超声乳化摘除术治疗)。比较两组患者的眼压及视力。结果治疗后,研究组的裸眼视力、最佳矫正视力、平均角膜散光度、手术源性散光度、眼压、BUT、Sit值下降幅度均优于对照组(P<0.05);两组患者治疗前后的SAI、CMT、角膜敏感度比较无差异(P>0.05)。结论应用角巩膜缘切口超声乳化摘除术治疗老年白内障患者,能够降低对角膜内皮细胞的损伤,且对眼压及视力的影响较小。

Objective To study the effects of phacoemulsification cataract extraction with different incisions on the intraocular pressure and vision of elderly cataract patients.Methods A total of 82 elderly cataract patients admitted to the Fourth People's Hospital of Shenyang were selected as the research objects,from April 2019 to January 2020,according to the wishes of the patients as the research group(n=41,phacoemulsification with limbal incision was performed)and the control group(n=41,phacoemulsification of corneal incision was performed).The intraocular pressure and visual acuity of the two groups of patients were compared.Results After treatment,the study group's naked eyesight,best corrected visual acuity,average corneal astigmatism,surgical astigmatism,intraocular pressure,BUT,and sit value decrease were all better than those of the control group(P<0.05);the comparison of SAI,CMT,and corneal sensitivity between the two groups before and after treatment showed no significant difference(P>0.05).Conclusion Limbal incision phacoemulsification for the treatment of elderly patients with cataracts can reduce the damage to corneal endothelial cells,and has less impact on intraocular pressure and vision.
