Effect of fine capsule treatment on the visual quality of diffractive multifocal intraocular lens

摘要:

目的：探讨精细化囊膜处理对衍射型多焦点人工晶状体视觉质量的影响。

方法：选取2017-03/2018-04于河北省眼科医院白内障科植入衍射型多焦点人工晶状体患者98例120眼，将其随机分为A组和B组，每组60眼。A组患者术中行前后囊膜抛光联合后囊膜连续环形撕囊，B组未行囊膜抛光及后囊膜连续环形撕囊。比较术后6mo时远、中、近视力，视觉质量、人工晶状体居中性及后发性白内障(PCO)发生率。

结果：术后6mo时A组UCDVA(0.096±0.032)、UCIVA(0.225±0.038)、UCNVA(0.093±0.022)均优于B组(UCDVA 0.259±0.056、UCIVA 0.426±0.040、UCNVA 0.155±0.059)(均P<0.05)。视觉质量A组优于B组(P<0.05)。术后6mo时A组患者人工晶状体偏中心量(0.025±0.005mm)小于B组(0.665±0.244mm)(P<0.05)。PCO发生率：A组：0眼； B组：Ⅰ级5眼(8.3%)，Ⅱ级3眼(5.0%)，Ⅲ级2眼(3.3%)。

结论：通过对植入衍射型多焦点人工晶状体的患者行前后囊膜精细抛光联合后囊膜连续环形撕囊术，增强了IOL稳定性，保持视轴区长期的透明，对提高术后患者的视觉质量和满意度起到了良好的作用。

Abstract:

AIM: To investigate the effect of fine capsule treatment on the visual quality of diffractive multifocal intraocular lens.

METHODS: Ninety-eight patients(120 eyes)with DMIOL implanted in cataract Department of Hebei Eye Hospital from March 2017 to April 2018. They were randomly divided into A group and B group. 60 eyes in each group. Group A patients were treated with anterior and posterior capsular polishing and posterior continuous circular capsulorhexis, while in B group the fine capsule treatment was not performed. The UCDVA, UCIVA, UCNVA, visual quality, intraocular lens neutrality and PCO incidence were compared 6mo after operation.

RESULTS: At 6mo after operation, UCDVA, UCIVA and UCNVA in group A were superior to those in group B. The difference was statistically significant(P<0.05). At 6mo after operation, the amount of eccentric intraocular lens in group A was less than that in group B. The difference was statistically significant(P<0.05). PCO incidence: group A: 0 eyes; group B: 5 eyes(8.3%)in gradeⅠ, 3 eyes(5.0%)in grade Ⅱ, 2 eyes(3.3%)in grade Ⅲ.

CONCLUSION: In order to enhance the stability of IOL and maintain the long-term transparency of the optic axis, we performed fine polishing of the anterior and posterior capsule and continuous circular capsulorhexis of the posterior capsule. These could improve the visual quality and satisfaction of patients after surgery.
