An integrated approach to the second correction of residual myopia after extraction of lenticula through a small access

Abstract

Purpose. To develop a new method for correction of residual myopia after the Smile surgery, to evaluate a functional effect of this type of surgical intervention. Material and methods. The study included patients with mild residual myopia after the Smile surgery, who were corrected for insufficient refractive effect using photorefractive keratectomy (PRK), CIRCLE and the original SPS technique (Smile post Smile). In order to assess changes in the parameters of the cornea and visual functions, a profound ophthalmological examination was performed before and after the operation with a multiplicity of 1 day and 6 months. Results. All patients had a good refractive and functional effect by six months after surgery, and the maximum increase in visual acuity was achieved already on the first day after CIRCLE and SPS. The highest satisfaction with the quality of vision was revealed in patients after SPS surgery. Conclusion. The results obtained after the correction of residual myopia by the SPS method (Smile post Smile) indicate that the developed technology is highly effective, safe and can be recommended for application in the clinical practice.
