The study design is to report a case series of bilateral implantation of the Apthera/IC-8 small aperature IOL in complex corneas and compare them to real world results.

Single surgeon, prospective evaluation of 38 eyes treated with the Apthera/IC-8 small aperature IOL.

The series includes patients (N-38 eyes) with normal corneas and Apthera/IC-8 IOL compared to patients implanted bilaterally in complex corneas (hexagonal keratotomy, small optical zone radial keratotomy with >8 incisions, small optical zone laser vision correction, or combinations of refractive procedures). The normal cornea group showed bilateral postoperative 1 hour results of 20/20; 20/25; 20/32; 20/40 (35%, 50%, 65%, 80%) and the complex cornea bilateral results at 1 hour results of 20/20; 20/25; 20/32; 20/40 (50%, 67%, 100%, 100%). Target refraction in all eyes was based on biometry measurements closest to -0.75D.

The bilateral implantation of the Apthera/IC-8 IOL in complex corneas performs well when compared to normal corneas. A myopic target is suggested of -0.75D based on FDA clinical trial outcomes from the United States series. AM and PM biometry helps patients outcomes to insure functional vision  throughout the day in patients with refraction fluctuations prior to surgery in the complex cornea series.
