TitleThe continuing quest to perform accurate IOL calculations in cataract surgery.
PurposePurpose: To evaluate the accuracy of intraocular lens (IOL) calculations with the LENSTAR®
MethodsMethods:
Design: Retrospective, case series.
Participants: 30 patients who underwent phacoemulsification + intraocular lens implant.
Intervention: All patients were evaluated preoperatively with objective refraction(OR), axial length based on ultrasonography(AXL) and LENSTAR®. On the one hand, IOL was calculated based on AXL and OR and on the other hand,the three calculated IOL’s of the LENSTAR® were documented. The difference (D) between the chosen IOL and the calculated IOL was noted for all methods. Patients were seen the first postoperative day and one month after surgery. Their best corrected visual acuity (BCVA) and OR were documented on each visit. Finally, we compared the documented D with the OR of the patients.
Main outcome measures: BCVA and OR after IOL calculation with LENSTAR® after 1 month of follow up.
ResultsResults: The preliminary results show that the calculation based on the Haigis method is the most accurate. In most cases the difference between the chosen IOL and the calculated IOL by this method is almost neglectable, whereas in other formulas, the difference is more notable. Statistical analyses will be illustrated on the poster.
ConclusionConclusion: The preliminary results illustrate a very good accuracy of the IOL calculations with LENSTAR®, with the Haigis Formula in particular.
