Abstract Details


Our aim is to evaluate possibilities of refractive surgery for patients with high myopia. We will compare different possibilities of refractive surgery and their indicating criteria. This topic is focused on laser methods (FemtoLASIK and ReLEx SMILE) and non-laser method (implantation of phakic posterior chamber intraocular lens, ICL). Each type of refractive solution has its own indication criteria, therefore the methods cannot be compared in absolute rates. The study shows results of surgery methods performed on patients of our eye clinic. Furthermore, we assess their postoperative values of UCVA and the complications, we found in different methods used.


Our study group includes a complex of 60 eyes for each of these 3 methods (ReLEx SMILE, FemtoLASIK, ICL). Dioptric range is from 6.25 to 10.0 spheric dioptres and to 3.5 cylindric dioptres. The age range is from 18 to 45 years.


FemtoLASIK is corneal laser procedure, where femtosecond laser creates flap and the second step is fotoablation of corneal stroma by excimer laser. Limitations are pachymetry under 500 micrometres, residual stroma tissue under 300 micrometres. ReLEx SMILE is corneal laser method where flap is not created, there is used only femtosecond laser. Limitations are residual stromal tissue under 250 micrometres and the dioptric range advised by producer. ICL implantation is reversible method. We used it in the cases when laser surgery is contraindicated or in border indications. Limitation is anterior chamber depth less than 2,8 millimetres.


One day after the surgery, BCVA was highest for patients after FemtoLASIK 0.87. One year after the surgery or before retreatment, the average BCVA for patients treated by FemtoLASIK was 0.78, for patients treated by ReLEx SMILE was 0.96 and for patients treated by ICL was 0.96. Average value of objective refraction one year after operation, before retreatment, are in FemtoLASIK -0,52 spheric dioptry, -0,5 cylindric dioptry, in ReLEx SMILE -0,11 spheric dioptry, -0,5 cylindric dioptry and in ICL -0,19 spheric dioptry and -0,12 cylindric dioptry.


All above described methods used for refractive surgery are useful and safe. They have different indication criteria and the type of selected method depends on the surgeon's experience as well. Implantation of ICL and ReLEx SMILE were proved to be more effective methods of refractive surgery in correction of high myopia compared to FemtoLASIK. There we found higher percentage of regression and next retreatment.
