Purpose: To share the experience of simultaneous binocular multifocal IOL implantation after LASIK with functional testing of reading quality change.
Methods: Patient (49 y.o. woman) who had previously undergone laser vision correction by LASIK for mild myopia (no history data).Standard preoperative diagnostic for IOL implantation was performed as well as multiformula IOL calculation. The reading ability changing was tested by Salzburg reading desk.
Results: Before the surgery the UDVA of each eye was 1.0 as well as VIS OU=1.0, UNVA 40 cm each eye 0.3, with sph +2.0 = 1.0, UVA 70 cm each eye 0.5 with sph +1.25 D = 0,7, objective refraction OD sph+0.5 Dptr cyl-0.25 Dptr ax 98, OS sph+0.75 Dptr cyl-0.25 Dptr ax66.
The patient underwent immediate sequential bilateral bilateral refractive lens replacement and implantation of a trifocal aspheric intraocular lens in the right eye and a trifocal toric aspheric intraocular lens in the left eye. We used the following IOL calculation formulas: ASCRS mean IOL power, Shammas formula, Barrett true K formula, Masket formula, Modified Masket formula, Haigis-L formula. 1 week postop: UDVA OU = 1,0, UNVA 40 cm = 1,0, UVA 70 cm = 0,7. The objective refraction OD was sph+0.0 D cyl-0.75 D ax163, OS sph+0.25 Dptr cyl-0.0 D.
Compliance with the modified algorithms of intra- and intraoperative behavior of the operating team, preparation of the patient, careful calculation of the IOL allowed to obtain the predictive refractive result with a high level of visual satisfaction and absence of undesirable postoperative phenomena.
The patient underwent the examination with Salzburg reading desk before and after the surgery, to confirm the excellent functional results of the treatment.
Conclusion: There are still discussions if it is reasonable to perform a simultaneous, same day, IOL implantation in both eyes, especially on eyes with previously operated corneas.
Our case let us confirm that having modern equipment, performing a multi formula calculation allowed us to achieve excellent functional and refractive results.
