Abstract Details



Purpose:

To develop the effective and safe surgical treatment technology of mature intumescent cataract.

Setting:

The Academician S.N. Fyodorov FSBI IRTC 'Eye Microsurgery' Tambov branch, Tambov, Russia.

Methods:

The surgical treatment results of mature intumescent cataract were analyzed in 62 patients. Preoperative Vis was pr.l.certa. Intraocular pressure (IOP) was P0=20.2 mm Hg. After the anterior capsule staining had been performed a cohesive viscoelastic agent was injected and a 1.5-2 mm capsulorhexis was created. The swelling lenticular masses were removed by means of an irrigation/aspiration system. The vacuum level was 600 mm Hg, aspiration rate - 35 mL/min. The nucleus was rotated by an irrigation/aspiration tip. The nucleus inclination and rotation helped to remove swelling lenticular masses from the posterior compartment of the lens bag. Next, a standard sized capsulorhexis was created and phacoemulsification with IOL implantation was performed. It allowed eliminating the Argentinean flag sign completely.

Results:

During the surgery two tears of the anterior capsule were observed, which didn't reach the equator and were converted to the continuous circular capsulorhexis. The postoperative visual acuity was 0.65±0.15 and depended on the status of the retinal macular zone. The postoperative IOP was P0=15.6 mm Hg. The removal of the swelling lenticular masses from the anterior lenticular compartment allowed releasing tension on the anterior capsule. The removal of the lenticular masses from the posterior compartment was achieved by rotating and turning the hard lens nucleus eliminating its tension on the anterior capsule and making it possible to create the standard sized anterior capsulorhexis safely.

Conclusions:

The creation of a 1.5-2 mm capsulorhexis allowed removing the liquescent lenticular masses from the anterior segment in an effective and safe manner. The nucleus inclination and rotation gave the opportunity to remove the liquescent lenticular masses from the bag posterior compartment and to eliminate the nucleus tension on the anterior capsule when creating a capsulorhexis. This made it possible to create a standard sized capsulorhexis safely, to avoid the Argentinean flag sign and to perform the cloudy lens phacoemulsification effectively. FINANCIAL INTEREST: NONE
