PurposeTo evaluate the surgically induced changes in refraction (sphere and astigmatism) and higher order aberrations by corneal incision for one year.SettingUniversity Hospital “Virgen de la Arrixaca”, Murcia, Spain.DesignRetrospective interventional case series.MethodsCorneal power, astigmatism and higher order aberrations (HOA) were calculated from corneal topography measured in 27 eyes prior to surgery and at 2 weeks, 1, 2, 3 and 6 months and 1 year following cataract surgery with 3.2-mm corneal incision. At every stage, optical changes were calculated as the difference between pre- and post-surgery data (in each follow-up) using the formulas of obliquely crossed cylinders for the refraction and Zernikes coefficients for HOA.ResultsAt 2 weeks after surgery the mean corneal values of induced sphere, cylinder and the root mean square (RMS) of HOA were +0.54±0.27 D, -0.77±0.32 D and 0.15 microns respectively. These parameters decreased significantly (p-values between 0 and 0.01) at 3 months to +0.33±0.27 D sphere, -0.50±0.24 D cylinder and 0.10±0.05 microns HOA and were stable at the next follow-ups. Induced spherical equivalent was around zero at all visits. The changes in HOA were mainly due to trefoil aberration.ConclusionsLinear corneal incisions do not change the spherical power but can induce significant values of astigmatism and trefoil aberration in the cornea. However, these changes revert fully or partially to preoperative values by the third month after surgery and remain stable with time.

Jordi Llovet. Adiós a la Universidad. El eclipse de las humanidades. Galaxia Gutenberg. 2011. isbn: 978.8481.099.157 A través de este libro el autor narra sus experiencias vividas a lo largo de cuarenta y tres años de trayectoria universitaria, desde que iniciase su andadura como estudiante en 1965, hasta llegar a catedrático en 2008. El título del libro encierra un doble significado: por una parte, hace referencia a la despedida del autor de su faceta de profesor universitario en activo, al tiempo que también remite a aquello que se apresura a calificar como el final (acaso no definitivo) de la pujanza o crédito de las humanidades en el seno de nuestras universidades y sociedad...
