Purpose:
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.
Setting:
Ophthalmology unit, department of Neurosciences, University of Verona, Verona Italy
Methods:
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.
Results:
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.
Conclusions:
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.
