Cálculo de lente intraocular en un paciente con antecedente de cirugía LASIK bilateral y colocación de implante intracorneal para presbicia

A 55-year old male with history of bilateral LASIK surgery for myopia, left eye LASIK retouch and right eye corneal inlay implantation for presbyopia correction presents with reduced visual acuity. Bilateral cataract is diagnosed and phacoemulsification surgery is performed after calculating intraocular lens power with Mackool's aphakic technique. This technique was compared with the results of four corneal evaluation platforms and two intraocular lens calculation formulas. Two months after bilateral surgery, uncorrected binocular distance vision was 20/25 and uncorrected binocular near vision was J6; the postoperative refractive error was within the expected range for the aphakic technique (± 0.75 dpt). Mackool's aphakic technique is less practical but the results are reliable. We recommend it in difficult cases where the structure of the cornea is altered due to previous surgery or disorders.
