Comparing two vision corrective laser eye surgery techniques

INTERVENTION: A randomized double trial: Topoguided femtolasik (contoura) will be performed in one eye and customized by asphericity (Custom‐Q) in the contralateral eye. In January 2019, the design of the research study began. After the approval of the ethics committee, the study started the screening of patients who would receive refractive surgery. On the day of the surgery, patients were randomized using a randomization program to choose the surgical technique that would be performed in the patient's right eye and the other technique in the contralateral eye. All patients performed a complete ophthalmological examination, including complementary exams. Both groups received the same treatment drops. Both techniques provide excellent results. The difference would be the form of laser ablation. Patients underwent ophthalmological examinations and complementary imaging exams on day 1, week 1, and months 1 and 3, and 1 year after the surgery. CONDITION: Myopia with or without astigmatism ; Eye Diseases PRIMARY OUTCOME: Visual acuity (logMAR chart) measured using a digital projector with and without correction at 1 day, 1 month, and 3 months post‐operatively SECONDARY OUTCOME: ; 1. Ephthelial remodeling in microns measured using an OCT Avanti that evaluates the epithelial thickness map generated by an automatic algorithm and divided into a total of 17 sectors (central, paracentral and mid‐periphery) preoperatively and at 3 months; ; 2. Cornea total root mean square (RMS) (total high order aberrations on Cornea surface) measured using corneal tomography with the Galilei G6 using the Zernike map preoperatively and at 3 months postoperatively; INCLUSION CRITERIA: 1. Myopic patients with or without astigmatism 2. Aged between 20‐35 years old 3. Spherical degree up to 8 and cylinder up to 3
