FEMTOSECOND LASER IN CATARACT SURGERY: TECHNOLOGICAL REDUNDANCY OR A NEW LEVEL OF POSSIBILITIES

Vitebsk State Medical University, Vitebsk,
The Republic of Belarus

This review presents modern data about the pros and cons of femtosecond lasers usage in cataract surgery. International scientific and medical databases “PubMed” and “Cochrane library” were used. The study showed that femtolaser assistance provides a new level of accuracy in different stages of the operation, which guaranties their standardization, unification and predictability. Using laser assistance in all patients, it is possible to get anterior-capsular holes of a given diameter within ±0.25 mm; if capsulorhexis is performed manually, such level of accuracy will be obtained only in 10% of the operated eyes. At the same time, it was found that despite the increase in the accuracy of the stages performed by femtosecond lasers, the differences in postoperative refractive indicators and visual acuity in patients who underwent phacoemulsification of cataracts with laser assistance are not higher than in the application of the standard technique. In addition, due to high cost of the equipment and lack of a significant effect in post-operative visual acuity, the widespread introduction of femtosecond lasers in cataract surgery is still doubtful. Despite the absent of consensus of experts about the clear advantages of laser assistance, this technique should be developed, for so that it provides opportunity to determine the influence of different stages on the final result of the operation and determine the direction of their further improvement and standardization of the stages creates the prerequisites for the use of ophthalmic robots.
