Jascha Wendelstein MD
​​​
​
Dr. Wendelstein was born in Munich, Bavaria, Germany, on August 16, 1988.
He is an eye surgeon specializing in cataract, refractive, and corneal surgery
at the Institute for Refractive and Ophthalmic Surgery (IROC) in Zurich,
Switzerland.
He is a member of two study groups: one with Achim Langenbucher and Peter
Hoffmann (Germany), and another with Kamran M. Riaz and David L. Cooke
(USA).
After studying medicine and nutritional sciences in Vienna, Austria, he completed his eye residency in 2022 in Linz, Austria. He finished his doctoral thesis on modern intraocular lens (IOL) calculation formulas under the guidance of Achim Langenbucher at the Department of Experimental Ophthalmology at the University of Saarland, Germany. Winning the renowned ESCRS Peter Barry Fellowship Grant in 2022 led him to IROC Zurich, where he deepened his knowledge in refractive and keratorefractive surgery procedures under the guidance of Prof. Theo Seiler, a pioneer and inventor of excimer-based refractive surgery and corneal crosslinking. Under Prof. Seiler, he won the 2023 Swiss ophthAWARD for “research with highest clinical relevance”. There Dr. Wendelstein performs around 1,000 laser vision correction procedures annually.
Scientifically, his main interests lie in the combination of IOL-based and cornea-based procedures, IOL calculation in challenging cases (keratoplasty, keratoconus, post-laser vision correction), IOL designs, refractive surgery, corneal power calculations, corneal/biometric diagnostic devices, biometry, bioptics, phakic and pseudophakic additive IOLs, and keratoconus and crosslinking.
Together with both study groups (and to his delight with several other members of the IPC), Dr. Wendelstein has published over 78 studies. Notable contributions include the Castrop formula for IOL calculation, the Castrop nomogram for arcuate incisions, the LHC and LION formulas for phakic IOL calculation, the CRW-Index (a screening tool to identify eyes after laser vision correction using biometry data), the Homburg Adelaide toric IOL nomogram and other prediction models for toric IOLs, prediction models for the axial lens position, IOL decentration and tilt, prediction models for ocular magnification and aniseikonia after cataract surgery, a translation model for CW chord to angle alpha, and a three-surface model to implement stromal curvature into corneal power calculations.
Besides IOL power calculations he also enjoys basketball and arts.
