Visumax laser platform

After Topical anesthesia, the patient was asked to xate on an internal light source. The procedure was done using the VisuMax laser platform (Carl Zeiss Meditec AG, Jena, Germany) according to the standard method. First, the posterior surface of the lenticule was incised from the periphery to the center and then the anterior surface was incised inversely. The lenticule creation parameters were as follows: cap thickness = 120 µm, cap diameter = 7.7 mm, optical zone = 6.5 mm, and transition zone = 0.1 mm for cases of moderate myopia, and cap thickness = 110 µm, cap diameter = 7.2 mm, incision, optical zone = 6.0 mm, transition zone = 0.1 mm for high myopia. In the postoperative period, 0.5% chloramphenicol eye drops (Sina Darou, Tehran, Iran) were administered four times a day for three days. Betamethasone 0.1% drops (Sina Darou, Tehran, Iran) were tapered as four times a day in the rst month, two times a day in the second month, and once a day in the third month) and preservative free arti cial tears (Hypromellose) were instilled four times a day for one month.

This study was a retrospective analysis performed at a private eye hospital in London, UK to evaluate the early clinical outcomes of the first SMILE procedures undertaken by three surgeons with the VisuMax laser platform (Carl Zeiss Meditec, Jena, Germany). The study population comprised 71 eyes from 37 patients (21 males and 16 females) with myopia, with or without astigmatism, (mean spherical equivalent refraction (SEQ) -5.61±2.25 Dioptres (D), ranging from -10.88 D to -1.25 D). The surgeries were bilateral in 34 patients, and three patients had unilateral surgery.
All surgeries were non-monovision treatments where the target refraction was plano (0 D) to achieve emmetropia. No attempt was made to correct presbyopia in the study population.
Inclusion criteria for the study were myopia treatment up to -10.00 D with ocular astigmatism up to -5.00 D, patients seeking to become more spectacle independent and seeking an advanced corneal refractive laser approach. Exclusion criteria were unstable refractive error, previous ocular surgery or trauma, ocular abnormalities or disease, progressive myopia or astigmatism and any systemic disease which could affect wound healing (e.g. diabetes). Informed consent was obtained and the study was performed in accordance with tenets of the Declaration of Helsinki.
