IOL calculations can be challenging in patients who have undergone corneal refractive surgery. In this original research paper, Vision Eye Institute’s A/Prof Michael Lawless, Prof Gerard Sutton, A/Prof Tim Roberts and their colleagues compare the prediction accuracy of different calculation methods, including standard keratometry (SK), measured posterior corneal astigmatism (PCA) and total keratometry (TK).

Below is a video summary of the paper’s findings by lead researcher, A/Prof Lawless.

The paper can be accessed online through Wiley Online Library and is open access for 90 days.

A/Prof Michael Lawless is one of Australia’s most experienced eye surgeons, having performed more than 30,000 surgical procedures. He is a clinical associate professor at Sydney Medical School (University of Sydney) and has expertise in refractive surgery, cataract and lens replacement surgery and corneal conditions. A/Prof Lawless practises at our Bondi Junction, Chatswood and Hurstville clinics.
