Abstract Details

Purpose:

The goal is to evaluate the clinical and functional results of femto-assisted phacoemulsification of a complicated cataract with simultaneous correction of corneal astigmatism in a patient with Weill-Marchesani syndrome.

Setting:

Kaluga branch of FGAU «NMIC «MNTK «Eye Microsurgery» named after acad. S.N. Fedorov»

Methods:

Sixty-year-old male patient with complicated cataract OD, Weill–Marchesani syndrome, moderate myopia, myopic astigmatism had phacoemulsification with femtosecond laser arcuate keratotomies (FLAKs) using a Femto LDV Z8 femtolaser. Uncorrected visual acuity was 0.02 with sph-7.0D cyl -4.5D ax 159=0.4. Keratometry data: Kmin 44.75 ax 160°, Kmax 47.62 ax 70°. Parameters of FLAKs, the relative positions of the main incisions, paracentesis and neat cuts were computed on VERION system. The depth of FLAKs was set 85% of the initial corneal thickness, and the localization diameter 8.0 mm. Data from the diagnostic module were sent to the surgical unit of VERION system.

Results:

The patient was satisfied with the improvement of vision, the postoperative period was uneventful. One, 3 and 6  months later, uncorrected visual acuity was 0.3, and with correction cyl. -1.5 ax 161⁰ - 0.8. The keratotopogram showed decrease of the cylindrical component by 3.5 diopters after 1 month of observation, after 3 and 6 months there was decrease by 3 diopters and remained stable. According to keratotopography, the localization of the FLAKs clearly corresponded to the planned VERION system, without the appearance of irregular changes in the anterior surface of the cornea. The IOL position was stable during follow-up.

Conclusions:

The development of new diagnostic technologies and modern capabilities of high-tech surgery help determine the optimal tactics for treating patients with cataracts complicated by severe defects of the ligamentous apparatus. The VERION system allows for high-precision calculation of the parameters of FLAKs. Topographic orientation with subsequent intraoperative navigation allows the surgeon to facilitate continuous precise control over the positioning of the axis of the astigmatic component, which contributes to the achievement of the planned compensation of the initial astigmatism of the cornea and the maximum possible visual acuity in the early postoperative period.
