Purpose:
To report the outcomes of combined cataract surgery with toric intraocular lens (IOL) implantation when performed in conjunction with transconjunctival sutureless pars plana vitrectomy.
Design:
Retrospective interventional case series.
Participants:
Consecutive series of 55 eyes of 51 patients from April 2007 to December of 2010.
Methods:
All eyes underwent combined simultaneous small incision cataract surgery, toric IOL implantation, and transconjunctival sutureless vitrectomy surgery.
Main Outcome Measures:
Postoperative visual acuity, postoperative astigmatism, and rotational stability of the IOL.
Results:
Preoperative best-corrected visual acuity was 0.32 ± 0.15 logMar (Snellen 20/43) and improved to 0.16 ± 0.10 (Snellen 20/29) postoperatively uncorrected (P < 0.01) and to 0.08 ± 0.11 best-corrected (Snellen 20/24) (P < 0.01). Preoperative astigmatism was 1.75 ± 1.0 diopters (D) (range, 0-4.75 D) and improved to 0.5 ± 0.50 D (range, 0-2.5 D) postoperatively (P < 0.01). Final measured postoperative IOL axis deviation from target axis was 4 ± 6° (range, 0-32). Final IOL axis was within 5° of target in 47 (85%) eyes, within 10 degrees of target in 51 (93%) eyes, and was within 15° of target in 52 (95%) eyes.
Conclusion:
Toric lens position and axis remained stable after implantation during combined cataract surgery and transconjunctival sutureless vitrectomy.
