Abstract Details

Purpose:

To evaluate the influence of preliminary marking of visual axis (VA) on functional results of ReLex SMILE operation.

Setting:

The work was performed in the Khabarovsk branch of the Federal State Autonomous Institution «S.N. Fedorov National Medical Research Center «MNTK «Eye Microsurgery» of the Ministry of Health of the Russia

Methods:

60 patients (60 eyes) with myopia and complex myopic astigmatism were under observation. They underwent ReLex SMILE and were divided into 2 groups. The main group consisted of 30 patients (30 eyes) who had marking of VA based on corneal light reflex using light filament of microscope. Other 30 patients (30 eyes) of the control group were operated without marking. UCVA and BCVA, spherical and cylindrical components of subjective refraction were studied on the first day and 1 month after operation, when change of corneal aberrations (Pentacam) was also analyzed. Patients’ complaints on quality of vision were also considered.

Results:

The analysis showed that postoperative values of UCVA, BCVA and refractometry were almost identical in both groups. The examination of refraction revealed 30% increase of vertical coma (p>0,05) in control group and absence of reliable change of studied aberrations in the main group. Besides, only one patient from the main group complained on presence of halo and glare effects against four patients from the control group.

Conclusions:

Preliminary marking of VA at ReLex SMILE operation leads to less influence on corneal aberrations in general, coma in particular, thus providing better quality of vision acuity of operated eyes.
