Clinical Advancements in Intraocular Lens Power Calculation Methods

Dear Colleagues,

Cataract surgery is one of the most common performed procedures worldwide. Additionally, patients are becoming more demanding in terms of refractive outcome and, therefore, hitting target refraction is more and more important. This is why the calculation of the optimal intraocular lens is a crucial factor for the success of cataract and refractive lens surgery and one of the main parameters for post-op patient satisfaction. This Special Issue is meant to highlight recent advances in IOL calculation, presenting innovative algorithms, biometric measurement techniques, and personalized calculation approaches.

Possible key technologies to optimize lens power selection could be artificial intelligence and machine learning. Additionally, new formulas such as the Barrett Universal II, Hill-RBF, and Kane formulas are already outperforming older generations of formulas, showing higher predictability for a wider range of eyes. The impact of cutting-edge biometric devices, including swept-source OCT technology, on calculation accuracy is also one factor of the current advancements in meeting postop expectations.

Beyond technological advancements, practical recommendations for improving postoperative refractive accuracy, particularly in patients with previous procedures such as corneal refractive surgery of silicone oil fill in retinal detachment eyes, are needed. In this Special Issue, we invite experts to submit studies on IOL calculation using modern or AI formulas, comparing biometry, and giving recommendations on which calculation method to use in complex eyes like those post-refractive surgery.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Clinical Medicine is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
