5 Key Takeaways

1

A 55-year-old female post-RK patient with glaucoma experienced significant visual deterioration and reconsidered contact lens use.
2

Corneal GP lenses with reverse geometry were recommended due to the patient's low endothelial cell density and contraindications for scleral lenses.
3

The fitting of corneal GP lenses resulted in improved best-corrected visual acuity of 20/30 OD and 20/25 OS after adjustments.
4

The patient reported excellent comfort with the lenses and stable intraocular pressure during follow-up visits.
5

A multidisciplinary approach was essential for successful lens fitting, ensuring visual rehabilitation and corneal health preservation.
