Keratoconus is a non-hydrostatic degenerative disease of the cornea in which the corneal tissue changes its shape over time. Depending on the type of condition, patients can improve their vision and quality of life by choosing appropriate contact lenses. The good news is that with the new technologies in the lenses’ construction, it is easier to find a comfortable and effective solution. Here, you will find information on the type of contact lenses for keratoconus and how to make a suitable decision.
Understanding Keratoconus
Keratoconus is a condition that results in the cornea becoming thin and irregular, conically shaped. Some of the signs and symptoms include: hazy vision, photophobia and impaired night vision. These problems become more pronounced as the condition advances, and ordinary glasses become less useful. Specially fitted contact lenses enhance vision for keratoconus patients.
Factors to Consider When Choosing Contact Lenses
Choosing the right contact lenses depends on several factors:
- Stage of Keratoconus: Soft lenses may be useful for early-stage patients, but patients at an advanced stage will need more specific treatment.
- Comfort and Wear Time: Think of lenses that suit your lifestyle and personal preferences of wearing lenses.
- Lifestyle Needs: Lenses that provide stability and durability can be valuable for active individuals.
- Professional Advice: Consulting an eye specialist ensures the best results.
Types of Contact Lenses for Keratoconus Patients
Keratoconus patients have a variety of contact lens options to choose from, tailored to different needs and stages of the condition:
Soft Contact Lenses
Soft contact lenses can be worn when the disease is in its early stage and the corneal surface is not much irregular. Although they can be helpful in this aspect, they do not completely improve severe vision problems as the disease advances.
Rigid Gas Permeable (RGP) Lenses
RGP lenses are small and hard, thereby providing a fitting for moderate keratoconus because they retain their shape on the eye. They form a smooth refractive surface which greatly enhances the quality of vision. Although they may take a shorter period to break in and be ready for use, they may take longer time to be comfortable.
Scleral Lenses
Scleral lenses are larger in diameter and sit on the white part of the eye called the sclera, and avoids the cornea. They offer high comfort and stability, which makes it suitable for the progressive keratoconus or the extreme type of the disease. Furthermore, the fluid reservoir under the lens helps to solve the problem of dryness and irritation.
Hybrid Lenses
There are two types of hybrid lenses: one with a rigid core and a soft periphery. It combines the advantages of RGP lenses and soft lenses hence is preferred by most patients who need both features.
Custom-Designed Lenses
Modern techniques of fittings enable the practitioner to produce tailored lenses that meet the specific topography of the patient’s corneal surface. These lenses provide the best vision correction and comfort to the wearer.
Advantages of Contact Lenses Over Glasses
Contact lenses are often the preferred choice for keratoconus patients due to their ability to:
- Treat irregular astigmatism of the cornea.
- Offer better and clearer vision than glasses while being more stable.
- Provide a wider field of view that no glasses can provide.
Challenges and Solutions in Choosing Contact Lenses
While contact lenses are effective, they come with challenges such as:
- Initial Discomfort: In most cases, patients have a short period of adaptation to the device. This problem is solved when its use is made more frequent.
- Hygiene Maintenance: Cleaning procedures are very important to avoid infections and to ensure that the lenses are always in good condition.
- Lens Wear Time: It may result in dryness when used for a long time. Lubricant eye drops can be helpful together with visiting an ophthalmologist.
The Role of Eye Care Professionals
A person with keratoconus should see an eye care professional for check-up from time to time. Professionals observe the advancement of the disease, check the correct fit of the lenses and adjust them if necessary. It also means that your lenses are well cared for in a way that makes them comfortable and effective in the long run.
