Abstract Details

Purpose:

to evaluate of the FemtoLASIK method results in an induced refractive error correction after optical-reconstructive surgery with iris-lens diaphragm implantation.

Setting:

The S. Fyodorov Eye Microsurgery State Institution, Russia.

Methods:

we observed 41 eyes (41 patients) with residual ametropy after the iris-lens diaphragm implantation in pre- and post-keratorefractive surgery, out of which 17 eyes were operated by the standard FemtoLASIK technology – group I, 24 eyes by the topography-guided FemtoLASIK technology – group II. The method of the laser correction was selected based on data of the keratotopography, central pachymetry, the localization of the scar and the state of anterior surface of the cornea.

Results:

after the keratorefractive surgery the spherical component decreased in the group I from -1.71±0.75 D to -0.32±0.11 D, in the group II from -2.34±0.15 D to -0.25±0.16 D. The average value of the cylindrical component also significantly decreased from 3.58±1.17 D to 0.65±0.22D after the standard FemtoLASIK and from 4.22±1.11 D to 0.42±0.34 D after the topography-guided FemtoLASIK (р<0.05). Uncorrected visual acuity compared with preoperative values significantly increased in the group I from 0.17±0.08 to 0.62±0.13, in the group II from 0.08±0.11 to 0.83±0.15. Loss of lines of corrected visual acuity was in no cases.

Conclusions:

The FemtoLASIK is effective and safe technology to achieve high functional results in the correction of residual ametropia in patients after optical-reconstructive surgery with iris-lens diaphragm implantation.
