I am dedicated to assisting the first-time contact lens wearer with a great first experience, especially teenagers. In addition, my passion has expanded to managing hard-to-fit contact lens cases such as Keratoconus, Pellucid Marginal Degeneration (PMD), post-transplant, and post-LASIK Ectasia.

In many hard-to-fit cases, patients may be wary of trying contacts due to previous poor comfort or visual experience. We are committed to providing the finest contact lens care and visual improvement.

Patients Discuss Keratoconus Contact Lens Fitting with Dr. Donna

Contact Lens Treatment

Since contact lenses come in many different designs, as specialists we will create a custom design that offers the best combination of vision, comfort, and eye health.

We will not rush you through the process of learning insertion and removal of contacts. In addition, we will provide you with a comprehensive understanding of contact lens care to ensure the best eye health and longevity of your lenses.

For patients with Keratoconus, fitting a contact lens can be difficult. This is especially true in advanced stages of Keratoconus where the cornea continues to bulge outward. A contact lens must be fit around this bulge and still maintain proper fit, comfort, centration, health and vision.

It is a common misconception that contact lenses halt the progress of Keratoconus. In fact, the lenses simply improve vision while the condition is developing. Yet, if the lenses are not fitted properly, the Keratoconus may worsen by scar tissue formation.

A Keratoconus contact lens specialist evaluates the cornea by using sophisticated computerized video keratography to provide a color topographical map of the eye’s cornea surface. This allows us monitor the Keratoconus and select the best lens design possible for the unique characteristics of your corneal surface.

In addition, a Keratoconus contact lens specialist may try several different lens designs to create a custom fit. Our practice has a multitude of contact lens fitting sets, which allows us to create a more customized fit than any other center in Los Angeles.

You can expect to spend an average of 2-4 hours in our office for your first visit. Depending on the complexity of your case and the lens design, expect 1-4 hours for subsequent visits. Non-Keratoconus soft contact lens fits will usually take 1-3 subsequent visits to finalize the fit. Keratoconus and other complex cases will typically require 6-8 visits over the first 6 months to obtain the best fit and vision.

Keratoconus Contact Lens Design

Six designs for maximizing vision, comfort and eye health:

  • HydraKone, KeraSoft, FlexLens or Soft KC Toric Lenses – Finally, soft lenses for Keratoconus patients! These lenses can provide improved comfort versus other designs. The vision with these specialty soft contact lenses designed for Keratoconus is better than traditional soft lenses and in many cases can provide vision comparable to RGP lenses. These lenses are ideal for those with mild to moderate Keratoconus.
  • Custom Piggy Back Contact Lens System – Although this involves wearing two lenses on one eye, most patients find that this can be one of the most comfortable fits for Keratoconus when an RGP alone cannot be tolerated. Most patients learn to insert these lenses quicker than it takes them to brush their teeth. The key with this system is that the soft lens actually protects the sensitive cornea. The soft lens can be customized to hold the RGP lens, which keeps the RGP lens in place and reduces the chance of losing the RGP lens.
  • Synergeyes – These lenses are the latest breakthrough in contact lens technology. The center of the lens is a highly oxygen permeable rigid material, while the outer skirt is a soft lens. You get the benefit and comfort of a Piggy Back System while only needing to insert a single lens. Dr. Weiss is actively involved in improving this technology and has completed a beta study, successfully fitting over 90% of patients in the newer lens design.
  • Rose K2 IC – Rose K lenses have been one of the longest and most widely used Keratoconus RGP lenses. The K2 version has a larger diameter which improves comfort. Also, it has a special design that helps address irregular corneas with better quality of vision compared to the original Rose K design.
  • Intra-Limbal Dyna-Z – Individually designed lenses based on topography readings. The visual results and comfort can be phenomenal due to larger diameter. Before making the jump to Scleral lenses, this is the lens to try.
  • Scleral Lenses – These are RGP lenses that rest out on the white portion of the eye. Amazingly these lenses are extremely comfortable because they do not rest on the cornea. It takes some time to learn to insert these lenses due to the large diameter, but once you get that down you will be amazed by the vision.

Contact Lenses To Improve Vision For Teenagers

Teenagers in greater numbers are seeking contacts as an alternative to glasses.

Deciding if contacts are right for teenagers is an important part of the discussion with an eye care professional.

Most teenagers will agree that they care about their appearance, but not all teenagers are ready for the task of proper contact lens care.

Contact lenses are a medical device, which require proper care and maintenance.

It is important to decide if a teenager is responsible and ready for contact lenses.

During a personal one-on-one consultation and examination with Dr. Donna and her contact lens assistant Monica, care and maintenance will be discussed. It is important to determine if your teenager is mature and responsible enough to follow these care and maintenance guidelines to ensure eye health.

Benefits of contact lenses for teenagers:

  • Improve Appearance, Improve Confidence
    Teenagers today often face multiple pressures socially. Finding a path to follow and not be hindered by appearance can improve self-confidence and help teenagers discover their place in the world. Glasses can create an artificial barrier between themselves and others and even their place in the world. Contact lenses can remove that barrier and open the world to many teenagers. They will experience an improved appearance that is more natural and they will feel more self-assured.
  • Improve Sports Performance
    Contact lenses are often considered superior to glasses during sports participation. Glasses can often fog up, slip down the nose, get knocked off easily and can even break during rough sports activity. Teenagers who wear contact lenses during sports participation are able to wear protective goggles to improve eye protection. Teenagers often report that they have improved vision with contacts over glasses and this can provide a competitive advantage.

Glasses Versus Contacts – Benefits

Limitations of Eyeglasses Benefits of Contact Lenses
Quality of Vision:The distance between the eye and the eye glasses can sometimes decrease the quality of vision and actually cause some visual distortion for patients with high prescription glasses. Quality of Vision:Contact lenses are placed directly on the eyes, which provides more natural vision and improved quality of vision. By eliminating the distance between the lens and the eye, the quality of vision is improved and visual distortion is reduced.
Field of Vision:Side vision, also referred to as peripheral vision, is less optimal in glasses due to the fact that glasses do not wrap around to the sides of the eye. Field of Vision:Because contact lenses rest around the entire portion of the eye responsible for vision, the field of vision improves. Side vision or peripheral vision is maintained.
Foggy Vision:Glasses can fog up with changes in the weather/temperature, while near water, or walking into areas with showers or steam, such as the gym or kitchen. Foggy Vision:Contact lenses (when properly maintained) do not fog up. This can enhance personal safety, not needing to worry about foggy vision.
Comfort:Often patients are bothered by the uncomfortable weight of glasses on the face, nose and and ears. Comfort can be improved by periodic tightening or other adjustment of glasses, however for many these changes are not enough to eradicate the discomfort. Comfort:Once contacts are properly fitted, patients typically report an increased sense of comfort because they no longer struggle with the weight of the glasses. Also, they eliminate the frustration of glasses frames slipping.
Sports Participation:Patients report glasses are a distraction while playing sports or participating in other active lifestyle activities. They can fall off, fog up or provide less than optimal vision. Sports Participation:Patient report that by eliminating glasses, they feel less distracted and more focused while participating in sports or other active lifestyle activities. Contact lenses are a favorite among athletes.
Sunglasses:Prescription sunglasses can be costly and can limit options for fashionable eyewear. Patients with higher prescriptions may be limited in the style of prescription sunglass lenses and frames available. Sunglasses:Contact lenses can open the door to fun and fashionable sunglasses, which can be more affordable than purchasing multiple pairs of costly prescription sunglasses. A whole wardrobe of fashionable, functional, affordable sunglasses is available to contact lens wearers.
Appearance:Glasses are an unnatural, distracting barrier between your eyes and the world. Appearance:Contacts don’t detract from your natural appearance; they let people see your eyes.

Out-of-Town Patients

We have patients who fly in from around the world to have contact lenses fit at our office.

The first visit will determine the lens parameters and the second or third visit are considered dispensing visits. Depending on the lens design, a typical schedule for the first visit will involve being seen on a Monday, Thursday and subsequent Tuesday.

After the first visit you will need to return 2-4 weeks later to assess the fit and determine any lens parameter changes. This visit is usually comprised of a Monday and Thursday visit in the same week.

After the second visit you will be advised to return in 2-6 weeks. This visit is usually on Mondays.

After the third visit you will be advised to return an additional 2-3 times over the next 3 months.

Once the fit is finalized, you will be scheduled to return on an annual basis. If your prescription changes and your lenses need to be altered, you will be seen for 3 appointments, typically a Monday, Thursday and subsequent Tuesday.
