“I use a simple analogy with patients –you can play any tune on a kazoo, but it will sound much better on a professional flute. The choice of instrument, or tool, makes a difference in the quality of the output. I work with the most advanced software and imaging devices to ensure your rigid lenses are the perfect, healthiest fit."
The science behind custom rigid lenses starts with an examination of your tear layer. Most people don’t realize the eye doesn’t have a uniform surface. In fact, each cornea has its own topography with microscopic differences in elevation, symmetry and shape – similar to the gradations on a topographical map.
Your corneal topography reveals itself in the unique profile of your tear layer. The science behind proper tear function is essential in understanding which type of contact lens may be best for you.
Dr. Rozenberg uses sophisticated software to analyze 10,000 points across the cornea’s surface, creating a color-coded map of the natural tear layer for each eye. The examination is painless and quick. He then begins the process of designing a new tear layer to work optimally with your rigid lens. The new tear layer is then designed to provide clear vision and promote a complete exchange of tears with each blink, keeping your eyes healthy and comfortable as you wear your new lenses.
Why are tears important?
Unlike soft lenses, rigid contact lenses float on top of the tear layer.
- Tears fill the space between the cornea and lens, conforming to the shape of the lens. The tear layer that covers your eye is important in determining the quality of your vision and the healthy compatibility with rigid lenses.
- All tears are comprised of a water layer, fatty layer, and mucus layer. The right composition of tears is important to help provide good vision, keep the eye nourished and protect the eye from irritants.
- One purpose of your tears is to flush out waste products such as carbon dioxide, heat, lactic acid, bacteria, dead cells - and bring in much-needed oxygen.
- Tears also form a film surface for light to enter. With each blink, the tear layer is refreshed and the cycle renews.
Just like a hiking map shows the different elevations of a trail, your tear layer reveals the topography of your cornea. Every cornea features unique distinctions in elevation, symmetry, texture and shape. No two are alike, not even the corneas of your own two eyes.
