ABSTRACT

A 55-year old male with history of bilateral LASIK surgery for myopia, left eye LASIK enhancement and right eye corneal inlay for presbyopia correction presents with diminished 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). The Mackool’s aphakic technique is more unpractical but the results are reliable. We recommend it in these difficult cases where several surgical procedures alter the structure of the cornea.
