Interventions

PROCEDURE

congenital/pediatric cataract surgery

All procedures are performed under general anesthesia according to the standard technique of congenital/pediatric cataract surgery with an intraocular lens (IOL) implantation. Paracentesis is performed at 2.30 o\'clock using a 20-gauge straight microvitreoretinal (MVR) knife; a high molecular weight ophthalmic viscosurgical devices (OVD) is injected into the anterior chamber. Then a 2.4 mm corneal tunnel incision is made at 11 o'clock with a disposable keratome knife 2.2 mm. Circular continuous capsulorhexis (≈ 5.5 mm). Сortical cleaving hydrodissection is followed by bimanual phacoaspiration in irrigation-aspiration mode. OVD is injected in the anterior chamber and an IOL is implanted in the capsular bag. Residual OVD is aspirated from the anterior chamber and behind the IOL and followed by IOL alignment. The surgery is completed with corneal hydration at the tunnel incision site.

DEVICE

Non-Toric IOLs

A folding hydrophobic acrylic IOLs AcrySof IQ SN60WF and Clareon SY60WF for the non-toric group (Alcon Laboratories, Inc.) ARE implanted.

DEVICE

Toric IOLs

A folding hydrophobic acrylic IOLs AcrySof IQ Toric SN6ATx and Clareon Toric CNW0Tx for the toric group (Alcon Laboratories, Inc.) were implanted.
