Outcome

Type Measure Description Time frame Safety issue
Primary Mean Change in Intraocular Pressure (IOP) on Operative Day IOP (fluid pressure inside the eye) was assessed using the study specified tono-pen and measured in millimeters of mercury (mmHg). Change was defined as the difference between immediate postoperative IOP and immediate preoperative IOP. A greater change in IOP may indicate a less stable posterior chamber and/or a more invasive surgery. Day 0 preoperative, Day 0 postoperative
Secondary Mean Conjunctival Edema Score at Week 1 Conjunctival edema (swelling) was assessed during examination by the investigator and graded on a scale of 0-3, where 0=Absent and 3=Severe. Each sclerotomy wound was graded as infusion, vitrectomy probe, and illuminator and the average of the three was the overall Conjunctival Edema Score at the visit. Only one eye (study eye) contributed to the analysis. Week 1 post operative
Secondary Mean Post-operative Pain Rating at Day 1 The subject was asked to rate post-operative pain in the study eye using a score of 0-10, where 0=no pain and 10=the worst pain imaginable. Day 1 post operative
