Femtosecond Laser–Assisted Surgery With Bilateral Implantation of Trifocal IOL
Purpose
To evaluate the visual and refractive results of bilateral implantation of trifocal intraocular lens in patients with femtosecond-laser assisted lens surgery.
Methods
A prospective case of series underwent bilateral fs-laser assisted cataract surgery (LenSx, Alcon) and trifocal diffractive IOL (AT LISA tri 839 MP) implantation for correction of presbyopia. Parameters evaluated include uncorrected near (40cm), intermediate (80cm) and distance visual acuity, spherical and cylindrical manifest refraction in a 6 months follow-up.
Results
A total of 32 treated eyes corresponding to 16 patients. All patients undergo routine fs-laser assisted cataract surgery and bilateral trifocal IOL implantation with a follow-up range from 3 to 9 months. The postoperative refractive results were mean spherical refractive error of +0,02 D and mean cylindrical subjective refractive error of -0,36 D. Postoperative visual outcomes in uncorrected monocular vision were at 6ft 0.94, intermediate 0.94 and 0.75 for near vision. The uncorrected binocular intermediate vision acuity were 0.8 in all patients, allowing no dependence of correction for desktop/computer work.
Conclusion
The trifocal lens AT LISA tri 839 MP provides near, intermediate and far vision. The assistance of femtosecond laser for presbyopic lens exchange demonstrates safety and consistency in these premium intraocular lenses.
