ABSTRACT
AIM:To observe and analyze visual quality changes of the patients with posterior capsule opacification ( PCO ) Nd:YAG 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 Nd:YAG 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 Nd:YAG 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 ) Nd:YAG laser posterior capsular dissection can help improve BCVA, reduce tHOA, increase MTF tHOA values, and significantly improve visual quality of patients.
