Post-TPS keratometric readings were used for presurgical planning, and the actual postoperative residual refractive astigmatism (RRA) was recorded. Pre-TPS keratometry was used to mathematically simulate the RRA that would have been obtained from the lens choice and astigmatism management without TPS treatment.Results: Following TPS treatment, the magnitude of astigmatism increased in 52% of eyes, decreased in 24%, and remained unchanged in 24%. Correspondingly, astigmatism treatment modality changed in 68% of eyes after tear film stabilization with TPS treatment. The type of astigmatism management increased (ie, shifted from no treatment to LRI or LRI to toric IOL) in 25% of eyes and decreased in 8%. Actual RRA ≤ 0.5 D was achieved in 76% of eyes, compared to simulated RRA ≤ 0.5 D in 40% of eyes (p=0.004).Conclusion: Stabilization of the tear film with TPS treatment resulted in less RRA than if pre-TPS keratometric readings had been used to determine the astigmatism management method and toric IOL power and axis.Keywords: dry eye cataract, meibomian gland dysfunction cataract, thermal pulsation treatment dry eye, astigmatism treatment cataract dry eyeMatossian CDove Medical Pressarticledry eye cataractmeibomian gland dysfunction cataractthermal pulsation treatment dry eyeastigmatism treatment cataract dry eyeOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 2283-2289 (2020)
