Abstract Details

PURPOSE:Purpose:

To evaluate the efficacy phacoemulsification of dense, brunescent cataracts and phacoemulsification in cases of a weak or partially broken ciliary zonules, using of Koh`s phaco spatula with sharpen edge (patent application). Phacoemulsification of the dense cataract is challenges for even the experienced cataract surgeon. The most difficulty in performing phacoemulsification on a dense cataract is the amount of energy, required to break up the nucleus for removing. The technique aims to reduce the amount of ultrasound energy during phacoemulsification of dense brunescent and subluxated cataracts.

Setting:

Clinic of Eye Microsurgery �â�€�œGlaz�â�€�, Ekaterinburg, Russia, clinicaglaz@mail.ru

Methods:

20 patients with dense or subluxated cataracts were operated. After performing two horizontal incisions, capsulorhexis and hydro dissection are performing. Phaco tip, deep inserted into the nucleus from the lateral side, holds the nucleus with a high vacuum. Koch`s spatula with sharpen edge is inserted through paracentesis from the nasal side, behind the edge of the nucleus moves toward the phaco tip. A horizontal chop and split the nucleus is performed. The fragments are removed with the use of the above technique. Patients were examined preoperatively and postoperatively at weeks 1, 2, 4, 8.

Results:

Using the above technique enabled us to operate successfully 16 (80%) patients. In 4 patients (20%) with subluxated cataracts, the standard CTR was placed in the capsular bag and fixed by transscleral suture.

Conclusions:

Phacoemulsification of dense, brunescent or subluxated cataracts, with using of Koh`s phaco spatula with sharpen edge, allows to reduce the amount of ultrasound energy during phacoemulsification and the risks and complications (zonules rupture, rupture of the posterior capsule, trauma of the corneal endothelial cells and others) of cataract surgery in such cases.
