Changes of visual quality after Nd:YAG laser posterior capsular dissection to the patient with after-cataract / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM:To observe and analyze visual quality changes of the patients with posterior capsule opacification ( PCO ) NdYAG laser posterior capsular dissection, including the change of the best corrected vision acuity ( BCVA ) , total high- order aberration ( tHOA ) , and the modulation transfer function ( MTF) . METHODS:In this prospective observational study, 100 cases of patients ( 100 eyes ) with posterior cataract underwent NdYAG laser posterior capsular dissection ( posterior capsular diameter dissected was 5mm or higher). The mean age was 65. 52±7. 01 years old. The change of the BCVA was collected. The tHOA and MTF under the 3mm and 5mm pupil diameter were assessed by iTrace respectively before and after NdYAG laser posterior capsular dissection. RESULTS:All the surgery went well without obvious intraoperative and postoperative complications happened. The preoperative BCVA was 0. 451 ± 0. 023 while the postoperative BCVA was 0. 763±0. 025. The difference of BCVA before and after Nd YAG laser surgery was statistically significant (PCONCLUSION: Patients with posterior capsule opacification ( PCO ) NdYAG laser posterior capsular dissection can help improve BCVA, reduce tHOA, increase MTF tHOA values, and significantly improve visual quality of patients.
