Introduction. Development and advancement of bilensectomy technique are essential, since the number of implanted phakic IOL is rising every year.
Purpose. To optimize the location of surgical instruments during phacoemulsification of the eyes with phakic intraocular lenses.
Material and methods. The work is dedicated to the simulation of liquid flows in ocular anterior chamber when performing bilensectomy. A few types of cataract phacoemulsification for an eye not operated before and an eye with implanted phakic IOL were considered.
Results. Washing time was set for bimanual and coaxial phacoemulsification as well as for coaxial phacoemulsification with PIOL. The integral rate in the central part of cornea (a measure of friction force) was 0.0032 m/s and 0.0015 m/s in the bimanual and coaxial surgery, respectively.
Conclusion. The data received allow pursuing further studies in this area that provides increasing of efficacy and bilensectomy safety.
