TrIPLe: Outcomes of a Trifocal IOL in Post-refractive Patients
Study Details
Study Description
Brief Summary
To compare the prediction error of ORA vs formula for post-LASIK cataract patients when PanOptix IOL was implanted. Using post-operative outcomes to determine if preoperative IOL calculations, including Barrett TK, Barrett Universal II, Hill RBF, ASCRS post-refractive calculator, or intraoperative aberrometry is more accurate when the two methods disagree in patients who have had previous refractive surgery undergo cataract surgery.

Detailed Description
The study will be non-interventional with data being collected prospectively and retrospectively between at least two surgical sites. All subjects will have previous LASIK and be at least 3 months post op PanOptix implantation. The study will enroll up to 200 patients and a statistical database will be created.

Outcome Measures
Primary Outcome Measures
- To determine if preoperative IOL calculations or intraoperative aberrometry is more accurate when the two methods disagree in patients who have had previous refractive surgery undergo cataract surgery. [Pre-op to 9 month visit]
Percentage of eyes within +/- .5D of target for each formula and ORA. Overall % of eyes that have a disagreement between the two methods
Secondary Outcome Measures
- Post-operative monocular visual acuity [3 to 9 month visit]
Monocular Uncorrected Distance, Intermediate, Near Visual Acuity
- Post-operative best corrected visual acuity [3 to 9 month visit]
Manifest refraction, Best Corrected Distance Visual Acuity, Distance Corrected Intermediate, and Near Visual Acuity
- Post-operative uncorrected visual acuity [3 to 9 month visit]
Binocular Uncorrected Distance, Intermediate, Near Visual Acuity, Best Corrected Distance Visual Acuity, Distance Corrected Intermediate, Near Visual Acuity
- Post-operative visual acuity [3 to 9 month visit]
Percentage of eyes with Uncorrected Distance Visual Acuity of 20/20 or better, 20/25 or better, and 20/30 or better
- Post-operative visual acuity [3 to 9 month visit]
Percentage of eyes with Uncorrected Corrected Intermediate Visual Acuity and Distance Corrected Intermediate Visual Acuity 20/20 or better, 20/25 or better, and 20/30 or better
- Post-operative visual acuity [3 to 9 month visit]
Percentage of eyes with Uncorrected Distance Near Visual Acuity and Distance Corrected Near Visual Acuity of 20/20 or better, 20/25 or better, and 20/30 or better
- Patient's quality of vision and reported side-effects [3 to 9 month visit]
