Abstract Details

Purpose:

to study the dependence of functional results and frequency of posterior capsular opacification (PCO) development from method of viscoelastic removal at phacoemulsification of senile cataract.

Setting:

The work was performed in the Khabarovsk branch of the Federal State Autonomous Institution «S.N. Fedorov National Medical Research Center «MNTK «Eye Microsurgery» of the Ministry of Health of the Russian Federation

Methods:

328 patients (328 pseudophakic eyes) underwent phacoemulsification of senile cataract using LensX and Infiniti machines, Alcon, and were divided into 3 groups. 102 eyes of the first group had OVD removal using irrigation-aspiration system. In 120 eyes of the second group, impulse irrigation was additionally used. 106 eyes of patients of the third group had OVD removal using combined technique, but IOL pneumocompression method was also applied. The type of IOL-posterior capsule interface and vision acuity (VA) were studied on the 1st postoperative day; VA, structure and transparency of posterior capsule of operated eyes were examined 12 months after surgery.

Results:

On the 1st postoperative day optimal IOL – posterior capsule interface had place in 84,3% of eyes in the third group, and in 61,5% and 32,1% of eyes in the second and first groups, respectively. At comparable values of UCVA and BCVA in all groups on the 1st postoperative day, 12 months postoperatively both parameters of VA were highest in the third group and minimal in the first group. The reason of VA worsening was PCO, which had place in 45.7% of eyes in the first group, and in 36.2% and 15.4% of eyes in the second and third groups, respectively.

Conclusions:

The conducted research showed that frequency of PCO development and stability of functional result of phacoemulsification depend upon the technique of viscoelastic removal. Combination of impulse irrigation method of OVD removal with IOL pneumocompression method allowed achieving optimal IOL – posterior capsule interface resulting in three times decreasing of PCO development in comparison with other techniques.
