Purpose:
|
To evaluate the clinical results of toric trifocal diffractive intraocular lens in eyes with cataract and mild keratoconus
|
Methods:
|
Five keratoconus patients (10 eyes) that had bilateral AT LISA 939 implantation were selected and had followed in 3-time
horizons of 1, 3, and 6 months. Patients were 46 to 65 years old age, corneal astigmatism of (2.00 D at 6.75 D) and cataract that all of
them needed cataract surgery. The distance, intermediate and near visual acuities, defocus curve, ocular aberrations, contrast
sensitivity, were measured as effectiveness criteria
|
Results:
|
Average of binocular uncorrected distance visual acuity (UDVA) improved from 0.72 log MAR±0.11 (SD) to 0.04±0.04
(P<0.05) log MAR, average of uncorrected binocular intermediate visual acuity (UIVA) (80 cm) improved from 0.52±0.07 log MAR to
0.14±0.04 (P<0.05) log MAR, and average of binocular uncorrected near visual acuity (UNVA) improved from 0.48±0.09 log MAR
to 0.02±0.07 (P<0.05) log MAR at one year, respectively. Contrast sensitivity testing showed acceptable results, the binocular
defocus curve corroborate were in appropriate good visual acuity even at the intermediate distances, by a gentle slope less than log
MAR 0.2 at 1.5 D, with regard to the best distance visual acuity at the 0 D defocus
|
Conclusion:
|
Trifocal AT LISA 939MP IOLs provided appropriate distances, near and intermediate of the visual results. Prediction
of the refractive results and optical performances were good.
