Abstract Details


To evaluate the effectiveness of  Customized IOL implantation to treat Astigmatism and Spherical Aberration in patients affected by Keratoconus or previously surgically treated for refractive issues.


Ophthalmology unit, department of Neurosciences, University of Verona, Verona Italy


Ten patients were enrolled, of whom a total of  sixteen eyes were examined. Ten eyes were affected by non-evolutive keratoconus, and six had already undergone Laser Refractive treatment. After filling a given Form, the factory sent a IOL with customized spherical and toric power, and spherical aberration. Follow-up examinations were performed up to 6 months postoperatively and included visual acuity (near at 40 cm and distance), aberrometry, and contrast sensitivity.


Six months postoperatively, mean natural visual acuity was 0,63 ± 0,21, whereas visual acuity with correction was 0,89 ± 0,32 with a refractive error in Spherical equivalent, if compared to the preoperatively target of -0,52 ± 0,67 D. Visual acuity near at 40 cm was 0,65 ± 0,14, and with correction it was 0,97 ± 0,19. Contrast sensitivity was found within Normal Range, whereas  total spherical aberration was 0,01 micron.


These lenses proved to be effective for Astigmatism and spherical aberration correction in previously surgically treated eyes, or affected by keratoconus, giving a good visual acuity and high visual quality.
