Scleral Contact Lenses – a new hope

SCLERAL LENSES

If you have actually been told in the past that you cannot wear contact lenses due to an irregular cornea or various other problems, you might wish to get a second opinion and also ask your ophthalmologist regarding scleral contact lenses.

Scleral contacts are large-diameter or larger in size than normal contact lenses or gas permeable contact lenses specially designed to vault over or cover the whole corneal surface area and also hinge on the "white" of the eye (sclera). In doing so, scleral lenses functionally replace the irregular cornea with a flawlessly or perfectly smooth optical surface area to correct vision problems caused by keratoconus and various other corneal irregularities.

Additionally, the space in between the cornea and the back surface area of a scleral lens acts as a fluid reservoir to provide convenience for individuals with extreme dry eyes that otherwise might not endure contact lens wear.

Types of Scleral Lenses

Scleral contacts are significantly bigger than conventional gas permeable General Practitioner contacts and have a diameter equivalent to or greater than that of soft contact lenses. The smallest sclerals are around 14.5 mm in diameter, and also the biggest can be approximately 24 mm.

How a scleral lens vaults over a misshapen cornea to assist somebody with keratoconus see far better.

Large-diameter scleral and semi-scleral General Practitioner lenses hinge on the sclera and vault over the irregular cornea of an individual with keratoconus, for better vision. Increase the size of generally lenses that are 18 mm or smaller are subcategorized as mini-sclerals.

The ordinary human cornea is around 11.8 millimeters in diameter, so also the smallest scleral contacts are developed to cover the entire} corneal surface area.

In contrast, the majority of traditiona General Practitioner contact lenses are 9.0 to 9.5 mm in size and cover only 75 to 80 percent of the cornea.

An additional category of gas permeable lenses bridges the size gap between traditional General Practitioner lenses and mini-sclerals. These lenses, called corneo-scleral lenses, normally are roughly 13 to 15 mm in diameter.

Corneo-scleral lenses often} are a great {option for people who require larger-than-normal General Practitioner lenses for betterconvenience}. They also are frequently used when contact lenses are required after LASIK or other corneal refractive surgical treatment to correct irregular astigmatism.

The dimension of lens used usually is identified by the level of complexity of the condition. Milder types of keratoconus and irregular astigmatism from corneal grafts as well as refractive surgical treatment frequently are conveniently managed with scleral lenses at the smaller sized end of the spectrum.

Smaller sized scleral and mini-scleral contacts can be much easier to apply, can be less expensive and need less} care products

Much more complicated problems, consisting of advanced keratoconus, pathologically dry eyes or serious eye surface condition that may call for a huge tear storage tank, commonly are fitted with bigger scleral lenses, as they have a lot more capability to hold liquid or bridge huge adjustments in corneal curvature.

Throughout your contact lens examination as well as fitting, your eye treatment expert will certainly establish the most effective scleral lens type and also size for your particular requirements.

Scleral Contact Lenses for Keratoconus

Several optometrists as well as ophthalmologists advise scleral contact lenses for a range of hard-to-fit eyes, consisting of eyes with keratoconus.

In instances of very early keratoconus, a common GP lens might be made use of.  Nevertheless, if the lens does not center correctly on the eye or moves excessively with blinks and also triggers discomfort, switching over to a large-diameter scleral contact lens might solve the problem.

Since scleral lenses are developed to rise the corneal surface and also hinge on the much less sensitive surface area of the sclera, these lenses usually are much more comfy for an individual with keratoconus.

Additionally, scleral lenses are developed to fit with little or no lens activity or movement during blinks as they are hinged on the sclera, making them much more stable on the eye, compared to conventional corneal gas permeable lenses.

Scleral Contact Lenses for Various Other Eye Troubles

Along with keratoconus, scleral contact lenses can be utilized for various other eye problems such as eyes that have actually undergone a corneal transplant, and also for individuals with serious completely dry eyes triggered by problems such as Sjogren's disorder, graft-versus-host disease (GVHD) and also Stevens-Johnson disorder.

Advancements in lens design technology are enabling makers to develop scleral lenses that can remedy a lot more problems than ever, consisting of bifocal sclerals for the correction of presbyopia.

Special-Effect Scleral Contacts

Often the term "scleral lenses" (or "sclera lenses") additionally is used to explain special-effect contact lenses that significantly change the look of the user's eyes.

Nevertheless, these costume contact lenses also called theatrical contact lenses, Halloween contacts or gothic lenses generally are soft lenses that bear little resemblance to scleral gas permeable contacts in -- apart from their big diameter size to completely mask the cornea. Likewise, soft theatrical contacts generally are made for aesthetic functions just and not for vision correction.

Scleral contact lenses are tailor-made for every user, so suitable scleral contacts needs better know-how as well as even more time than fitting conventional soft or GP contact lenses.

Typically, computerized maps of the curvature of the whole cornea are produced to assist in the lens installation, as well as a number of test lenses of various dimensions and also curvatures might be related to the eye during the fitting process.
