Bottom Line: All patients refused using rigid gas permeable contact lens because of intolerance.All patients were followed-up for 28 months with a complete ophthalmic examination and corneal topography every two months.Improvement of BCVA of the cases was remarkable.

ABSTRACT

Objective: To present success of Toris-K contact lenses in keratoconus and traumatic keratopathy with irregular corneal surface.

Methods: Toris-K contact lenses were used to treat 7 eyes of 4 patients with traumatic keratopathy (Case 1) or keratoconus (Case 2, Case 3, and Case 4). All cases had a complete eye examination before the contact lens application. The case with traumatic keratopathy was a 32-year-old male who had corneal penetrating injury due to hobnail strike 23 months ago. The other 3 keratoconus cases were females at the age of 14, 16 and 22 years old. They had high myopia and irregular astigmatism due to keratoconus. All patients refused using rigid gas permeable contact lens because of intolerance. Toris-K contact lenses were fitted on all eyes. All patients were followed-up for 28 months with a complete ophthalmic examination and corneal topography every two months.

Results: Improvement of BCVA of the cases was remarkable. All cases were comfortable with their Toris-K contact lenses for 28 months. There was no significant distortion on the lenses during follow-up period.

Conclusion: Toris-K lenses may be an effective alternative treatment option for the patients with keratoconus and traumatic keratopathy, especially who cannot tolerate rigid gas permeable contact lenses.

Mentions: Case 1 was a 32-year-old male who had laser-assisted in situ keratomileusis in both eyes 6 years ago and corneal penetrating injury to the right eye 23 months ago. Fig-I After three months the primary corneal suturing, cataract extraction was made with phacoemulsification surgery in another ophthalmology clinic. After removing the corneal sutures, his best corrected visual acuity (BCVA) of the right eye was 20/100 with spectacles. RGPCL applications were unsuccessful because of advanced corneal surface. Fig-II BCVA of the left eye was 20/20 with glasses (-0,50 spherical -0,25 cylindrical with the axis of 15). Dilated fundus examination was unremarkable bilaterally. Intraocular pressure was within normal limits in the right (digitally) and left eye (Goldmann applanation tonometry) respectively.
