What is the Success Rate of Scleral Lenses? Full, Mini, and Semi-Scleral Lenses Explained

If you’ve struggled with traditional contact lenses or glasses, you may have heard about scleral lenses—a specialized option for those with unique vision needs. These lenses aren’t just a last resort for eye conditions; they’ve transformed the lives of countless people right here in Tacoma and the surrounding areas. Scleral lenses offer high success rates for patients with keratoconus, severe dry eye, post-surgical corneas, and even high prescriptions that don’t correct well with standard lenses.

How Do Scleral Lenses Work?

Unlike traditional contacts that rest on the cornea, scleral lenses vault over the cornea and sit on the sclera (the white part of your eye). This design creates a fluid reservoir between the lens and the cornea, keeping the eyes hydrated and reducing irritation.

This makes scleral lenses particularly beneficial for patients with:

• Keratoconus (irregular corneas)

• Severe dry eye syndrome

• Corneal transplants or post-surgical complications

• High astigmatism or extreme prescriptions

• Post-LASIK ectasia

• Corneal scarring or damage

Thanks to their custom fit, scleral lenses often restore clear, stable vision even when other options have failed.

Full Scleral Lenses

Full scleral lenses are the largest type, typically ranging from 18 to 24 mm in diameter. They completely vault over the cornea, providing a protective, moisture-rich environment for the eye.

Success Rate:

• Very high for severe keratoconus, corneal irregularities, and chronic dry eye

• Patients in Tacoma with extreme corneal conditions often find these lenses life-changing

• Some adaptation time is needed, but most patients adjust well and appreciate the comfort

Mini-Scleral Lenses

Mini-scleral lenses are slightly smaller than full scleral lenses, typically ranging from 15 to 18 mm in diameter. They offer a great balance between comfort and effectiveness, making them a popular choice for many of our patients in Tacoma.

Success Rate:

• High for moderate keratoconus and dry eye

• Easier adaptation than full scleral lenses, while still offering excellent vision correction

• Often preferred by patients who want better breathability without sacrificing hydration

Semi-Scleral Lenses

Semi-scleral lenses are the smallest of the three, ranging from 13 to 15 mm in diameter. They bridge the gap between traditional gas-permeable (GP) lenses and full scleral lenses. These lenses offer a more natural fit for patients who don’t need as much corneal vaulting but still benefit from the stability of a larger lens.

Success Rate:

• High for mild corneal irregularities or mild keratoconus

• Works well for patients who struggle with traditional gas-permeable lenses but don’t need full scleral coverage

• May not provide the same hydration benefits as full or mini-scleral lenses, but still offers significant comfort improvements over standard RGPs
