Scleral lenses have revolutionized the field of vision correction for people with irregular corneas or astigmatism. These specialized contact lenses, known for their larger size and unique design, offer a range of benefits. In this blog, we’ll explore different types of scleral lens designs, highlight some of their benefits, and explain the advanced technology to fit these lenses.
Types of Scleral Lens Designs
Scleral lenses come in various designs. Two notable types are mini-scleral lenses and toric scleral lenses. Mini-scleral lenses are larger than traditional contact lenses but smaller than full-sized scleral lenses. They vault over the cornea, resting on the sclera (the white part of the eye) while leaving a small space between the lens and the cornea.
Toric scleral lenses, on the other hand, are designed to correct astigmatism (a condition where your eyes have irregular curves) by using different strength corrections in different parts of the lens.
Benefits of Scleral Lenses
Scleral lenses offer a host of benefits for diverse vision needs. They can enhance visual acuity, correct refractive errors, and mitigate visual distortions. These lenses are particularly advantageous for individuals with irregular corneas, offering sharper vision and alleviating discomfort. Scleral lenses also provide hydration and alleviate dry eye symptoms, promoting ocular health and comfort.
Furthermore, post-corneal surgery, scleral lenses aid in visual rehabilitation, protecting the healing cornea while delivering stable vision correction.
Mini-sclerals
Mini-scleral lenses offer similar advantages in a more compact form. They provide effective correction for irregular corneas and offer a comfortable fit. Mini-scleral lenses bridge the gap between comfort, visual correction, and ease of use, making them an excellent choice for individuals with various corneal conditions.
Toric
Toric lenses cater specifically to individuals with astigmatism, addressing irregular corneal or lens shape. These lenses offer clear vision, improved contrast sensitivity, and reduced eye strain. With precise astigmatism correction, toric lenses provide individuals the opportunity to experience clearer vision and enhanced visual quality, improving their overall visual experience in daily activities.
Hybrid
Hybrid lenses, a combination of rigid gas-permeable (RGP) lenses and soft lenses, offer a promising solution for patients who require both stability and comfort. These lenses have an RGP center for visual correction and a soft lens skirt that rests on the sclera for improved comfort. Hybrid lenses provide excellent vision correction while reducing the risk of dislodging lenses and providing all-day comfort.
We Use Advanced Technology at Vision i Care
To ensure the best possible fit and comfort, advanced technology plays a crucial role in scleral lens fitting. Corneal topography is a non-invasive technique that maps the surface of the cornea, giving detailed information about its shape. This information helps optometrists customize the scleral lenses for each patient's unique eyes, allowing them to fit lenses for maximum comfort and effectiveness.
Ocular surface mapping is another powerful tool that optometrists use. It assesses the health of your eye by looking at the ocular surface and tear film, identifying any abnormalities or dryness that might affect how you wear your lenses. By addressing these issues before fitting scleral lenses, we can improve the lens-wearing experience for patients and minimize potential complications.
Scleral lenses have transformed the lives of people with irregular corneas or astigmatism, providing great visual clarity and comfort. With advancements in technology and innovative fitting techniques, eye care professionals can now customize scleral lenses to meet the unique needs of each patient. Whether it's utilizing corneal topography, ocular surface mapping, or exploring hybrid lens options, the fitting process has become more precise and individualized.
If you have an irregular cornea or astigmatism, consider discussing the potential benefits of scleral lenses with your optometrist. Your journey to clear and comfortable vision starts with a comprehensive examination at Vision i Care and a conversation about the advanced options available.
