Contact Lens Exam

At Vision Eye Max, LLC, we strive to meet all of your eye and vision care needs. Corrective lens evaluations and prescription management are provided by our optometrist in Katy. After a comprehensive eye and vision evaluation, Dr. Thanh-Sang Pham will discuss the variety of contact lens options with you to select the type that best fits your vision needs and lifestyle. If you suffer from dry eye, allergies, or recurring eye infections, speak with our staff to determine whether contact lenses are right for you.


Prior to prescribing contact lenses, Dr. Pham determines what level of vision correction you require. Refractive error (commonly known as nearsightedness, farsightedness, or astigmatism depending on the error) is evaluated by measuring how the eyes focus when a series of different lenses are placed in front of them. An optometrist may use either a phoropter or an automated instrument to take these measurements. To schedule an appointment for a vision evaluation with our Katy optometrist, call (281) 502-8900 today.

Corrective Lenses

After determining the level of refractive error, Dr. Pham works with you to determine whether contact lenses or glasses are best for your lifestyle. If you suffer from certain conditions, such as dry eye or allergies, glasses may be the most comfortable corrective solution. Contact lenses are available in either soft or rigid gas-permeable form. Contact lenses need to be changed daily, weekly, bi-weekly, or monthly, depending on what type of lens you select. Specialized contact lenses, such as bifocal contact lenses, are also available for patients with special eye conditions. Call us at (281) 502-8900 if you are interested in learning if contact lenses are a good fit for you.

Hard to Fit Contacts

Many people grew up wearing glasses hoping that one day they would be able to wear contact lenses instead and not have to worry about cumbersome frames. Unfortunately, traditional contacts are not always the best fit, and in the past, many have been told that they are stuck with their glasses. Today, more people are able to take back the contact lens option by choosing hard to fit contacts.

What Are Hard to Fit Contacts?

Hard to fit contacts are specialty contact lenses for those with various eye conditions that make traditional contact lenses uncomfortable or ineffective. The type of hard to fit contacts that are best for you depends on your vision and eye health. Some common conditions that lead to the need for special contacts include:

  • Astigmatism – a variance in the cornea that causes irregular vision distortion.
  • Dry Eyes – a condition where eyes feel either dry and itchy or watery due to the inability of the eyes to make tears properly.
  • Presbyopia – an age-related condition that results in problems focusing at both near and far distances.
  • Keratoconus – a progressive condition that causes bulging corneas and distorted vision. When contacts can be properly fitted, they allow for better vision than traditional eye glasses.
  • Giant Papillary Conjunctivitis – excess protein in tears, daily clean gas permeable lenses or disposable lenses, sometimes aided by eye drops.

Types of Hard to Fit Contacts

Gas Permeable Contacts

Semi-rigid lenses that allow for more oxygen to reach the eyes.

Piggybacking Contact Lenses

A rigid gas permeable lens set on top of a soft contact lens to assist with comfort.

Scleral Contact Lenses

These are contacts with a larger diameter than traditional contacts that offer better security over irregular corneas.

Hybrid contacts

Hybrid contacts are scleral contacts that are soft along the perimeter, but have the rigid gas permeable lens in the center.

Custom soft contacts

Custom soft contacts commonly have features such as higher water content. These are often used by those with dry eyes.

Toric Contact Lenses

Contacts that are shaped differently than standard lenses in order to accommodate astigmatism.

Multifocal on Monovision Contacts

Multifocal contact lenses work like bifocal or trifocal glasses, where looking through different parts of your eye allows you to see your best at various distances if you have presbyopia.

Another option used by those with Presbyopia is to use monovision. With monovision contacts, one eye is corrected for nearsightedness, while the other is corrected for farsightedness, and the eyes learn to team together in order to see at all distances.

​​​​​​​Not all vision problems can be corrected in a straightforward way. Those who require hard to fit contacts need to work closely with their optometrists to find the right type of contacts for their unique vision problems.
