The "Transplant" Myth
Decades ago, if your keratoconus advanced to a certain point, a corneal transplant (Penetrating Keratoplasty) was the inevitable conclusion. Many general ophthalmologists still operate under this outdated paradigm.
The Truth: With modern Scleral Lens technology, corneal transplants are now rarely necessary. They are reserved for cases with severe scarring where light literally cannot pass through the cornea.
Comparison: Scleral Lenses vs. Transplant
| Factor | Scleral Lenses | Corneal Transplant |
|---|---|---|
| Invasiveness | Non-Surgical | Major Surgery |
| Recovery Time | Instant (Day 1) | 12 to 18 Months |
| Risk of Rejection | 0% | Lifetime Risk |
| Visual Outcome | Often 20/20 | Unpredictable (High Astigmatism common) |
Why Sclerals Should Be Your First Choice
A scleral lens essentially replaces your irregular cornea with a perfect, smooth optical surface derived from the lens itself. It creates a "tear reservoir" that constantly bathes your eye in fluid, treating the severe dry eye that often accompanies keratoconus.
Before you sign up for surgery, get a second opinion from a Scleral Lens Specialist. The vast majority of "surgery" cases we see are actually just "complex fit" cases that can be solved non-invasively.
