Steps to wear Toric Contact Lenses for Astigmatism

Astigmatism is one of the most common yet vastly misunderstood vision problems. It is essentially a refractive error, which means the eye has a problem with focusing the light. The eye affected with astigmatism fails to focus light on the retina and thereby affects clear vision.


Astigmatism is one of the most common yet vastly misunderstood vision problems. It is essentially a refractive error, which means the eye has a problem with focusing the light. The eye affected with astigmatism fails to focus light on the retina and thereby affects clear vision. The most common symptom of this is blurred vision and if left untreated it can cause eye strain, headache and squinting.


This common eye problem can be detected during a routine eye examination and the doctor can easily detect the amount of astigmatism by shining a light into the eye and introducing a series of lenses between the eye and the light. This process of detection is called retinoscopy. Usually, the doctors recommend Toric lenses for astigmatism to help the patients have a clear vision.


The Toric lenses are a special type of contact lenses that are made to correct astigmatism. They are made of soft silicone hydrogel or gas permeable materials. One of the unique features of Toric lenses is that unlike the ordinary spherical lenses, these type of lenses have different powers in the lens. This implies that the Toric lens must remain firmly in one position for best vision.


Steps to wear Toric lenses?


The process of wearing Toric lenses are exactly same as wearing normal contact lenses. However, the only major difference is that these lenses must have the right orientation before you put it in the eye.


Step 1


Before you touch the lenses, wash your hands and dry them clean, preferably with a lint-free towel. In case, the lenses get stuck to the side of the case or the lid, shake the lenses gently to dislodge it and make it easy to pull off with hands.


Step 2


Always, wear one lens at a time. Before you put it in the eye always rinse it well with the sterile saline solution.


Step 3


Before you put the lens in the eye, it is always advisable to first check the lens, if it has any flaring edges at the top or not. If you see flared edges or a rim at the top, the lens is inside out and you may have to turn it back to ensure that the right side is out.


Step 4


Check the orientation of the lens, the heavier or the thicker side of the lens should be at the bottom always. Some Toric lenses for Astigmatism have a small mark on the lens to help identify the bottom portion easily.


Step 5


Hold the eyelids wide open and look straight ahead as you place the lens over your eyes. Placing the lens correctly is critical; blink your eyes a few times to set the lens correctly in position. Step 6 To remove the lens, hold the eyelids wide open and gently pinch out the lens with the index finger and the thumb. Step 7 After you remove the lens out, put in the saline solute to disinfect before putting back in the case.
