Abstract

PURPOSE
This study aimed to investigate factors that cause after-cataract such as diabetes, intravitreal gas injection during vitrectomy, and other factors in relation to the vitrectomy.
METHODS
The relationship between the vitrectomy and the frequency of Nd:YAG laser posterior capsulotomy was investigated in a sample of 947 monitored patients' eyes that underwent cataract surgery. The patients' eyes were classified into Group 1, which comprised 715 patients' eyes that underwent cataract surgery only, Group 2, which comprised 152 eyes that underwent both vitrectomy and cataract surgery at the same time, and Group 3, which comprised 80 eyes that underwent cataract surgery after vitrectomy. The age, gender, diabetes status, gases injected during the vitrectomy, and other factors were investigated.
RESULTS
It was found that 50 eyes (6.99%) in Group 1 received the posterior capsulotomy, 28 eyes (18.4%) had the procedure in Group 2, and 16 eyes (20.00%) had the procedure in Group 3, respectively. In Group 1, 21 eyes (8.86%) that received the posterior capsulotomy were from diabetic patients, 20 eyes (19.8%) were diabetic in Group 2, and 10 eyes (21.73%) were diabetic in Group 3. In Group 1, 29 eyes (6.06%) were from non-diabetics that received posterior capsulotomy, 8 eyes (15.68%) were from non-diabetic patients in Group 2, and 6 eyes (17.64%) were from non-diabetic patients in Group 3. In the group that had vitrectomy with gas injection, 6 eyes (25%) received the posterior capsulotomy in Group 2, and 10 eyes (24.39%) had the procedure in Group 3, respectively, while those in the group that had vitrectomy without gas injection included 22 eyes (17.46%) in Group 2 and 6 eyes (15.38%) in Group 3.
CONCLUSIONS
The Nd:YAG laser posterior capsulotomy was more frequently applied to patients who underwent vitrectomy, younger patients, diabetes patients, and patients who had vitrectomy with gas injection.
