Abstract Details

Purpose:

To define the effects of intracorneal rings FERRARA 320 arc  (AJL) implantation in eyes with advanced keratoconus.

Setting:

Medical Center MAVIT, Warsaw, Poland

Methods:

FERRARA 320 intracorneal rings were implanted in 8 eyes of 8 patients (age from 26 to 66 years) with advanced keratoconus stage from KK3 to KK4. Preoperative K max was from 54,3D to 82,0D, minimal pachymetry was from 361um to 496um. Femtosecond laser Visumax ( Carl Zeiss Meditec) was used to create intracorneal channels. Operations were performed between 03.2018 to 03.2019, local anesthesia (drops) was used in all cases. (film from the operation will be presented)

Results:

The UCVA improvement was achieved in all cases from 1 to 8 Snellen lines, BCVA from 1 to 5 Snellen lines, Kmax decreased from 4,6D to 17,7D (difference between preoperative and postoperative maximal curvature of anterior surface). All eyes had corneal asphericity improvement, Vogt's striae decreased or even disappeared.

Conclusions:

Intracorneal rings FERRARA 320 arc implantation is an effective method of improving visual acuity and quality of vision in eyes with advanced keratoconus . Due to femtosecond laser application the operation is much safer than in manual method. Rings help to slow the keratoconus progression and can delay the need for a corneal transplantation.
