Abstract Details

Purpose:

The aim of this study was to assess clinical results of transepithelial photorefractive keratectomy (T-PRK) in patient with bilateral post-infectious corneal opacities in combination with hyperopia and irregular astigmatism

Setting:

The S. Fyodorov Eye Microsurgery Federal State Institution, Moscow, Russia

Methods:

20-year-old men presented low bilateral UCVA as well as BCVA due to anterior central stromal corneal opacities in combination with hyperopia and irregular astigmatism. This patient underwent two consecutive surgeries: clear lens extraction with toric IOLs implantation for refractive error correction and the T-PRK using MicroScan excimer laser 500 Hz (Optosystems, Russia) for the “fine tuning”on both eyes. IOL power calculation was performed at the IOLMaster. The ablation profile was calculated using the KeraScan software (Optosystems, Russia). Examination included: UCVA, BCVA, refraction evaluation, corneal thickness a Fourier domain optical coherence tomography before and 1 year post-op.

Results:

Pre-op data: OD: UCVA - 20/100, spherical component– +2.5 D, cylindrical component– -8.0 D, BCVA – 20/34, central corneal thickness – 518 μm; OS - UCVA - 20/67, spherical component– +2.5 D, cylindrical component– -7.0 D, BCVA – 20/34, central corneal thickness – 509 μm. 3 months after IOL implantation: OU - UCVA - 20/50, BCVA – 20/29; OD - spherical component– -2.0 D, cylindrical component– -1.75 D; OS - spherical component– -1.5 D, cylindrical component– -1.5 D. 9 months after T-PRK: OU – UCVA and BCVA – 20/25, spherical component– -0.25 D; OD - cylindrical component– -0.5 D, central corneal thickness – 456 μm; OS - cylindrical component– -0.25 D, central corneal thickness – 457 μm

Conclusions:

This clinical case shows that combined technology included clear lens extraction with IOL implantation & T-PRK with Russian made excimer laser and is a possible method for visual rehabilitation in patients with anterior stromal corneal opacity opacities in combination with hyperopia and irregular astigmatism and allows achieving a high clinical and functional result
