Wavefront Guided Scleral Lenses
In some cases vision with scleral lenses, though improved, may still have some residual blur. This residual blur is caused by higher order aberrations. These higher order aberrations are responsible for doubled, overlapped, ghosted vision with glare, flare, starburst and halos. In these cases, the addition of highly customized wavefront guided, higher order aberration correcting scleral lenses can further improve your vision.
Vision Simulations of Traditional Scleral Lenses & Wavefront Guided Scleral Lenses
These optics are considered High Definition optics as the clarity is improved over traditional optics. Dr. Gelles was the first to use this technology in the North East United States and is currently the only doctor trained to do so in the state of New Jersey.
At the Cornea and Laser Eye Institute, Dr. Gelles’ research has found these lenses provide an average 50% percent reduction in aberrations and 1 or more lines of visual acuity improvement over traditional scleral lenses. He is currently running a clinical trial to evaluate vision improvements with this technology.
Wavefront Guided Scleral Lenses for Keratoconus and Irregular Astigmatism: This study will evaluate the outcomes of wavefront guided scleral lenses in order to improve vision and reduce higher order aberrations in keratoconus and irregular astigmatism.
If you are interested in participating in this study please schedule a consultation to evaluate your candidacy.
Indications for Wavefront Guided Scleral Lenses
Irregular Corneal Conditions:
Corneal Ectasia: These are diseases characterized by weak and thin corneal tissue resulting in an irregular cornea shape. Examples include conditions such as keratoconus, keratoglobus, pellucid marginal degeneration, and corneal ectasia after surgery.
Post-Keratoplasty: A keratoplasty is also known as a corneal transplant. These surgeries are used when the cornea is severely scarred or have extremely advanced disease. They can involve the replacement of all or select layers and areas of the cornea. After transplantation the cornea is smoother and clearer but irregularities still exist. Examples include penetrating keratoplasty (PK), deep anterior lamellar keratoplasty (DALK), corneal tectonic grafts (patch grafts), and epikeratophakia.
Post-Corneal Surgery: In very rare cases, after a corneal procedure to reshape the cornea, the corneal surface may become irregular in shape. Examples include after laser assisted in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), radial keratotomy (RK), or intracorneal ring segment (Intacs, Keraring, MyoRing, Ferrara Ring).
