Contact Lenses & Glasses Free Vision Correction
Individuals seeking glasses free vision correction should consider all of the following options: contact lenses, orthokeratology and vision correction procedures.
Over 96% of individuals with refractive errors choose to wear contact lenses for the purpose of glasses free vision improvement. Even with contact lens wear, many still wear glasses at home. Additionally, contact lenses, though great at correcting vision, still require daily maintenance as well as daily application and removal.
For those who are looking to eliminate the use of any vision correcting aids, such as glasses or contact lenses, they should consider a vision correction procedure. Additionally if you have discontinued contact lens and returned to glasses you may still achieve successful glasses and contact lens free vision with a vision correction procedure.
At the Cornea and Laser Eye Institute, our philosophy, for those with normal corneas, is to provide glasses free vision correction for life. We offer every type of contact lens and every vision correction procedure. Dr. Peter S. Hersh and Dr. Steven A. Greenstein are among the nation’s foremost experts in vision correction procedures and were instrumental in the development of procedures such as LASIK. Dr. John D. Gelles is renown for his expertise in contact lenses. Whichever glasses free correction you choose, you are working with an expert in the field.
Understanding Vision and Refractive Errors
Blurry vision is the result of a misaligned focus of the eye, referred to as a refractive error. This can present as nearsighted, farsighted, or astigmatism. For those with normal eyes, this refractive error can be adequately corrected with spectacles, traditional soft contact lenses, specialty contact lenses, orthokeratology, or refractive surgery. For those who choose contact lens options, there are a variety of contact lenses to improve vision for the following refractive errors:
Nearsightedness: Myopia with or without astigmatism
Farsightedness: Hyperopia with or without astigmatism
Age-related farsightedness: Presbyopia (difficulty reading)
Disparity between eyes: Anisometropia
No intraocular lens: Aphakia
Contact Lenses and Reading Glasses
Everyone at some point in their life will require reading glasses. For those looking to reduce or even eliminate dependency of reading glasses there are a variety of contact lens options. These may be referred to as multifocal contact lenses, progressive contact lenses, monovision contact lenses, extended depth of focus contact lenses or bifocal contact lenses. Each technology has its place but the most important thing to know is there are contact lens options to reduce or even eliminate the need for reading glasses.
Contact Lenses Options
Routine Soft Contact Lenses
Most patients are familiar with standard soft lenses. These lenses are mass-manufactured in a process called cast molding. The lens materials and parameters are generally limited to fit the average shape, size, and refractive power needs of a normal eye. Due to these limitations standard soft lenses must be carefully selected based on the curvature, size, and physiology the individual’s eye. Though these lenses are highly successful for most individuals with normal corneas, some patients will experience issues with inadequate vision or discomfort due to the limited parameters. This is where custom contact lens option become necessary.
Custom Soft Contact Lenses
Custom soft lenses can solve these issues. Unlike standard contact lenses which could be described as “one size fits most”, custom soft lenses are not limited to the typical parameter constraints of the average normal corneal population. Custom soft lenses are lathe-cut one at a time and can be produced in a nearly unlimited range of curvatures, diameters, materials, and virtually any refractive powers allowing for success where standard soft lenses are inadequate.
Custom Corneal Gas Permeable (GP) Lenses
Corneal GP lenses are the classic method of vision correction with a contact lens. These lenses are lathe-cut one at a time and can be produced in a nearly unlimited range of curvatures, diameters, materials, and virtually any refractive power for fit the individual. Additionally, because of the rigid material, these lenses allow for a higher quality of vision compared to soft lenses. Additionally, specialized optics can be included to reduce or eliminate the need for reading glasses.
Custom Hybrid Lenses
Hybrid lenses utilize a GP center with a soft lens skirt, so they have characteristics of both GP and soft lenses. Various hybrid lens designs exist, with multiple geometries to accommodate a variety of corneal shapes. The newest generation of hybrid lenses are entirely custom. They are lathe-cut one at a time and can be produced in a nearly unlimited range of curvatures and virtually any refractive powers allowing for success where soft lens vision is inadequate. Optically, these lenses offer GP lens levels of clarity and these lenses can offer specialized optics to reduce or eliminate the need for reading glasses.
Custom Scleral Lenses
Scleral lenses are typically used for corneal irregularity and ocular surface disease but these lens can be used for those with normal corneas. These lenses are available with an abundance of unique modifications to accommodate the ocular shape. Scleral lenses are lathe-cut one at a time and can be produced in a nearly limitless range of curvatures, diameters, and materials. Scleral lens optics can incorporate any refractive power correction.
