Table 1 Preoperative Risk Factors and Their Corresponding Point of Value in Our Risk Stratification System

Risk Category	Score
1. Previous pars plana vitrectomy	1
2. Corneal opacity	1
3. Small pupil (<3mm)	1
4. Shallow anterior chamber depth (<2.5mm)	1
5. Age >88 years	1
6. High ametropia (>6D of myopia or hyperopia)	1
7. Posterior capsule plaque/posterior subcapsular cataract	1
8. Posterior polar cataract	1
9. Guttae	1
10. Post-LASIK	1
11. Alpha blockers	1
12. Dense/brunescent cataract	3
13. Pseudoexfoliation syndrome	3
14. Phacodonesis	3

Figure 1 Risk score distribution. Of 530 patients, the majority had a risk score of 0 or 1.

Figure 2 Rates of intraoperative complications. Of 530 cases, 4.7% experienced posterior capsular rupture, 3.8% had vitreous prolapse, and 1.5% developed dropped nuclear fragments requiring pars plana vitrectomy.

Figure 3 Intraoperative complication rates stratified by diabetic status. 245/530 (46.2%) eyes were in patients with diabetes. Of these, there was a trend toward higher intraoperative complication rates compared to patients without diabetes; however, differences did not reach statistical significance.

Figure 4 Intraoperative complications stratified by level of training. There was not a significant association between level of training and rates of intraoperative complications.
