Abstract Details

Purpose:

To estimate the effectiveness of penetrating exchange autokeratoplasty in elderly people with secondary endothelial-epithelial dystrophy (EED) of the cornea and pseudophakia by using comparative analysis of the biological, optical and refractive results of the surgery.

Setting:

St.-Petersburg branch of Sv. Fyodorov “Eye Microsurgery Clinic”

Methods:

A comparative analysis of the results of 16 surgerys of  penetrating exchange autokeratoplasty (the main group) with the results of 16 surgerys of PK with nonconserved donor cornea (control group) was performed. The average age of patients was 73.7 ± 11.5 years. In both groups corneal pathological changes were represented by leukoma of category II-IV,  that developed during the progression of corneal EED on pseudophakic eyes. All of them underwent penetrating exchange autokeratoplasty with intake of keratotransplantat with a diameter of 7.5-8.0 mm from the blind eye in 11 cases, in 3 cases after its enucleation.

Results:

The postoperative period in both groups was uneventful, except signs of tissue incompatibility manifested like keratouveitis in 2 patients in the control group. In the main group clear grafts were observed in 14 eyes, partially clear - in 2 eyes. In the control group clear grafts were observed in 9 patients, partially clear in 5, dull in 2 patients. 1.5 ± 1.2 years after surgery CDVA in the main and control groups was, respectively, 0.16 ± 2.08 and 0.12 ± 1.06 (p 0.05). The  resulting level of visual acuity in both groups was  mainly due to the  age-related macular degeneration.

Conclusions:

The progression of corneal endothelial-epithelial dystrophy (EED) in elderly patients after phako with IOL implantation determines the need to find the optimal method of keratoplasty to restore the corneal transparency. Penetrating autokeratoplasty in elderly patients is an effective and safer method than the penetrating keratoplasty with nonconserved donor cornea.
