目的探究分析不同手术方案对白内障手术患者视力恢复和屈光度水平的影响,为临床治疗提供参考依据。方法选取白内障手术患者126例为研究对象,患者均采取超声乳化和人工晶状体植入术治疗,随机分为观察组和对照组,各63例,观察组采用2.0透明角膜不缝合自闭式切口,对照组采用3.5 mm自闭式无缝线透明角膜切口,分析两组患者视力恢复以及屈光度等变化。结果术前,两组患者视力、手术源性散光无明显差异,经过治疗,两组患者视力均得到显著提高(P<0.05),观察组患者在术后3 d(0.72±0.25)、1周(0.74±0.16)、1月(0.73±0.28)和3月裸眼视力(0.75±0.31)均显著高于对照组术后3 d(0.49±0.21)、1周(0.52±0.26)、1月(0.56±0.24)和3月裸眼视力(0.57±0.18)(P<0.05)。观察组术后3 d、1 w、1月、3月手术源性散光均显著小于对照组(P<0.05)。观察组术后3 d(87.3%)、1周(76.2%)、1月(74.6%)、3月手术源性屈光度改变率(73.0%)均显著低于对照组3 d(96.8%)、1周(92.1%)、1月(88.9%)、3月手术源性屈光度改变率(85.7%)(P<0.05)。两组患者屈光度均显著降低(P<0.05),实验组手术源性屈光度改变值显著低于对照组(P<0.05)。结论白内障手术采用2.0mm自闭式无缝线透明角膜切口有助于患者视力的恢复,减少屈光度变化幅度,具有积极的临床应用价值。
Objective To explore the effects of different surgical procedures on visual acuity and refractive power of cataract surgery patients and provide reference for clinical treatment. Methods 126 cases of cataract surgery were selected as the research object. All patients were treated with phacoemulsification and intraocular lens implantation. The patients were randomly divided into observation group and control group, with 63 cases in each group. The observation group received 2.0 clear corneal incision, In the control group, a 3.5 mm incision of clear corneal incision was used to analyze visual acuity and diopter changes in both groups. Results Before operation, there was no significant difference in visual acuity and surgical astigmatism between the two groups. After treatment, visual acuity was significantly increased in both groups (P <0.05) (0.74 ± 0.16), January (0.73 ± 0.28), and uncorrected visual acuity (0.75 ± 0.31) in March were significantly higher than those in the control group after 3 days (0.49 ± 0.21), 1 week 0.56 ± 0.24) and uncorrected visual acuity (0.57 ± 0.18) in March (P <0.05). The astigmatism of the observation group at 3 days, 1 week, 1 month and 3 months after operation was significantly less than that of the control group (P <0.05). In the observation group, the surgery-induced diopter change rate (73.0%) was significantly lower than that of the control group (96.8%) after 3 days (87.3%), 1 week (76.2%), January (74.6% 1 week (92.1%), January (88.9%), and the rate of surgical-sourced refraction (85.7%) in March (P <0.05). The diopter of both groups were significantly lower (P <0.05), and the change of surgical source diopter in the experimental group was significantly lower than that of the control group (P <0.05). Conclusions The use of 2.0 mm incision of the transparent corneal incision in the treatment of cataract can help to restore the visual acuity of the patient and reduce the amplitude of the refraction, which has a positive clinical value.
