Toric Contact Lenses for Astigmatism

Astigmatism is a condition that is caused by an irregular shape of the cornea - the clear part of the eye that covers the iris and the pupil.  The cornea is usually smooth, round, and spherical but in an astigmatic eye, the cornea turns into a shape that is not spherical and develops a second curve.  One of the primary duties of the cornea is to focus light onto the retina which enables you to see clearly.  When the cornea is out of shape and develops two curves, this creates two focal points therefore causing blurred vision.

The irregular shape of the eye makes it hard for traditional contact lenses to fit and provide clear vision and therefore requires specialized contact lenses such as toric lenses or rigid gas permeable lenses (RGPs).

What are Toric Contact Lenses?

Toric contact lenses are designed to correct astigmatism and custom made to fit the eye of the patient. Rather than having a perfectly spherical surface like standard contact lenses, toric lenses have a more oblong shape made to accommodate the shape of the astigmatic eye.  Toric lenses can be made of either soft or rigid gas permeable (RGP or GP) lens material, however the soft toric lenses are more common.

Toric contact lenses are also designed in such a way that the lenses stay in place on the eye to maintain proper vision. Sometimes as the eye moves or blinks the lens can rotate considerably on the eye.  If this rotation continues with a soft toric lens, a rigid gas permeable lens might be more effective.  Rigid gas permeable lenses have a longer initial adjustment time, but once this has passed they are usually just as comfortable as soft contact lenses and they are often easier to care for.

Toric lenses are available in every wearing schedule from daily disposable to long-term wear.  In some cases you may even find colored toric contact lenses.  Due to the customization required, toric lenses tend to be more expensive and may take more laboratory time to make than traditional lenses.

If you have astigmatism, finding the right fit for your contact lenses is essential.  Speak to your Houston eye doctor today for a full assessment to determine which type of toric lenses will work best for you to help you see and feel your best.

We are pleased to announce that all three of our Vision Source locations will be reopening for service during the week of May 4th, 2020.

During this difficult time, we have made adjustments to our services to ensure the health and safety of your patients, our staff, and our Doctors.

For the Protection of Our Patients, we have implemented the following procedures in our clinics:

Limited Appointment Scheduling - in order to ensure we are able to properly disinfect and adhere to Social Distancing Guidelines set forth by our local authority.  Certainly, urgent and emergency patients will be prioritized.

Fever Free Environment - Temperatures will be taken upon entering the clinic of all patients, staff, and doctors.  Anyone with 99.5 degrees or higher will be asked to reschedule.  Anyone who is taking a fever-reducing medication such as ibuprofen or acetaminophen will be asked to reschedule once the medication is clear from their system so we can be sure of an accurate temperature reading.

Pre-Screening Questionnaire - We will continue to ask any patient with URI symptoms to reschedule their appointment until they have been asymptomatic for 3 days or have a negative COVID test.

Face Covering - We are requiring everyone entering our clinics to wear some type of facial covering such as a homemade mask, scarf, bandana, or handkerchief.

Wash hands and sanitize - Upon entering the office, everyone will be asked to sanitize their hands.  Additionally, we will request they sanitize their hands before re-entering the business area.

All Vision Source staff with direct patient contact will be required to wear a mask.

Social Distancing - We are limiting the number of patients in our office and are asking, when possible, only the patient enters our clinics for their visit.  Please ask the person with your patient to stay in their car.  We can text them if they need their assistance.

When scheduling patients, we will be:

  1. Asking them if they have been diagnosed with COVID or been in contact with someone who has been diagnosed with COVID.  In those cases, we will postpone seeing the patient unless emergent.
  2. We will ask if they have any current symptoms of COVID.
  3. They will be notified that upon arrival to our office they will have their temperature taken.
  4. We will ask the patients NOT to bring family members with them into the office and we ask patients to wait in the car until they are called inside for their appointment.
  5. We will ask the patient to bring their own mask or face covering.  All of our doctors and any staff who will have direct patient contact will be masked.

Thank you for your support and understanding during these unprecedented times.

Please stay safe and healthy.
