PACHECO SERRANO, José Edilberto et al. Radial keratotomy versus radial minikeratotomy: Experience in "Ramón Pando Ferrer" Hospital. Rev Cubana Oftalmol [online]. 2000, vol.13, n.1, pp. 0-0. ISSN 1561-3070.
In this hospital, radial keratotomy is performed sice 1995. We propose that shorter incisions have some effect and cause less corneal weakness, since dicreases susceptibility to severe complications from traumata of daily life. This notion encouraged us to carry out a study to observe behaviour of shorter incisions in our service, and in the event of positive results, implementation of the technique so that our patients to benefit from it. Results from application of two refractive surgical techniques to repair a moderate to slight myopia are compared. 38 patients were selected from 20 to 40 years old, presenting with myopia between -2 and -6 dioptries, and astigmatism under to -0,75 dioptries. We performed conventional radial keratotomy in right eye, and radial minikeratotomy in lef eye in the same patient. Average variations were as follow: in the right eye: sphere (in D dioptries) from -3,38 to 0,32, cast from -0,48 D to -0,45 D, keratotomy from 44,75 to 41,21 D. In left eye: sphere from -3,38 D to -0,44 D, cast from -0,44 to -0,38 D, and keratotomy from 44,83 to 41,80. There was an improvement from 44,83 to 41,80. There was an imporvement of visual acuity with no glasses of 0,61 in right eye, and of 0,59 in the left one. In both techniques there weren´t statistically significant differences, with the advantage that new technique decreases risk of early rupture from the least corneal injury.
