Abstract Details

Purpose:

The capsulorhexis is considered by many experts the most important step in phacoemulsification and has a long learning curve. Technical difficulties may became it discontinuous, decentralized, oval, large or small, and may compromise all surgery. For this it requires a lot of training, which can be done in any surgical service, using materials that simulate the human lens capsule. With the objective to avoid iatrogenies, we search to improve and facilitate the capsulorhexis training.

Setting:

Conquista Eye Hospital (Hospital de Olhos de Conquista)

Methods:

Capsulorhexis training was improved by the development of stamp with fast drying ink containing a design of two concentric circles, one of 11mm in diameter (simulating the size of the cornea) and another of 7mm (simulating the size pupil in the mean mydriasis), two parallel lines radial to the 'cornea' circumference with a distance of 3 mm between them (simulating the main incision, limiting the trainee to work in this space). This design is stamped in 100% polyester packaging to bake food and the trainee initiates the simulation of the capsulorrexe, making use of the microscope, tweezers and insulin needle.

Results:

Improvement of the trainee performace was observed, leading to shortening of the learning curve in the human eye surgery. There was greater familiarity with the microscope, better perception of stereopsia, greater manual ability, providing overall improvement in the surgical technique.There was a decrease in problems caused by defective capsulorrhexis: fewer capsule ruptures, decentralized, captured and tilted intraocular lenses (IOLs), IOL fixation surgeries, reoperations, pars plana vitrecotomy (due to IOL dislocation for the posterior segment and also due to retinal detachment).

Conclusions:

In view of the results obtained, it is suggested that this type of training be applied in ophthalmologist training services. This would undoubtedly reduce the incidence of iatrogenesis in phacoemulsification.
