Intraocular Lens Calculator Algorithm for Presumptive Diagnosis of Intraocular Lenses

Surgical intervention for cataract extraction, together with the insertion of a toric intraocular lens in patients with corneal astigmatism, has undergone significant advances. It is now recognized as a safe and comfortable procedure, with positive results that contribute to the improvement of visual acuity. In this context, the main objective is to achieve emmetropia through optical correction. For this purpose, the research focuses on the precise determination of spherical and cylindrical power, as well as the appropriate placement of the toric intraocular lens, based on the information obtained through ocular biometry and keratometry. Consequently, a support tool has been developed for the presumptive diagnosis of patients with no history of ocular surgery. The results of such diagnosis are used to calculate the final position of the toric intraocular lens, with the aim of optimizing the patient’s visual field. These results are also shared with the specialists of the “Santa Lucia” clinic in Quito, Ecuador.
