Abstract Details

Purpose:

To evaluate the quantity and quality of vision. To estimate changes in corneal shape, stability of the refraction results and patient's satisfaction.

Setting:

Kyiv Eye Microsurgery Center

Methods:

23-year-old female presented requesting laser vision correction. Patient complained about imperfect vision with glasses. She admitted that 3 year ago she had a good vision without spectacles. After examinations mild myopia, myopic astigmatism, progressive keratoconus stage 2 on both eyes was diagnosed. Corneal Crosslinking on both eyes with an interval of 10 days was performed. 9 months after CXL corneal parameters and vision were stable so that it was decided to perform Partial Surface Topography-guided (corneal WFGT) ablation (LASEK).

Results:

After one-year follow up there were improvements in 6 of 7 topography indices, suggesting an overall improvement in corneal shape. There was small improvement in UCVA and more in BCVA. Despite wearing glasses, the patient was satisfied with her vision. She admitted that the quality of the vision had improved noticeably: shadows and ghostly images had disappeared. The woman evaluated her vision without glasses as good, and with glasses as excellent.

Conclusions:

CXL stabilized the cornea and surface ablation improved the quantity and quality of vision by reducing the amount of irregular astigmatism. Only part of refractive error can be corrected due to limits for avoiding potential risk of ectasia. The goals of the treatment were achieved and the patient was satisfied with the result.
