ARIAS DOMINGUEZ, Mildred Karelia; MILAN GONZALEZ, Nelson; LAZO PEREZ, María Aurelia  and  FUENTES PELIER, Damaris. Use of the corneal topography for a better professional training in patients with pterigion surgery. MEDISAN [online]. 2021, vol.25, n.3, pp.675-685.  Epub June 11, 2021. ISSN 1029-3019.


Pterigium surgery is demanded as a skill in the first year of the residency and the topographical evaluation is a key element to evaluate corneal modifications and to improve clinical -surgical skill of training surgeons.


To determine the corneal modifications in patients with pterigium surgery in the Ophthalmological Center from Santiago de Cuba, from January 2019 to the same month in 2021, in whom a topographical evaluation was carried out before and after the surgical procedure.


Female sex (60.4 %), age group 40-49 (5.8 %), the disease grade II (43.4 %) and induced astigmatism as the most frequent complication (33.9 %) predominated. Average corneal power suffered a variation of 43.25 D and 45.75 and the topographical astismatism decreased from 4.75 to 3.55 D.


With the use of topography it was proven that there are corneal modifications derived from pterigium invasion to the cornea and from the surgical manipulation.

Keywords : pterigium; corneal topography; conjunctival autoplasty; astigmatism; surgical procedure.
