A Scan Eye Test for lens power calculation

A Scan – Lens Power Calculation in Mumbai

A-Scan is used for lens power calculation before a cataract surgery and is performed in all patients undergoing this surgery at Eye Solutions in Mumbai.  A-scan ultrasound biometry, commonly referred to as an A-scan, is a diagnostic test used by ophthalmologists. It provides data on the eye length for calculation of intraocular lens power.

Why is this A Scan needed before Cataract Surgery ?

 When cataract surgery is performed, the natural lens in the eye is removed and replaced with an artificial lens (IOL). Regardless of the type of lens used, standard or Premium, measurements of the eye are needed before surgery. These measurements are highly precise.  When combined with special computerized calculations, these allow the surgeon to choose the lens power that is appropriate for each eye. Because each eye has a different size and shape, the power in the lens needed is different for each eye. For this reason, an A Scan is always required prior to cataract surgery.

These days cataract surgery is not only a surgery to get rid of the cataract.  Over the years it has gradually become like a refractive surgery.  In other words apart from removing the cataract, ophthalmologists also want to leave the patient glass free.  Thus, ophthalmologists need to calculate the lens power with a high level of accuracy.  An A scan in Mumbai is available with most ophthalmologists and also at Eye Solutions.

Will I feel anything during the scan ?

No. All you have to do is place your chin on the chin rest of the instrument and a picture is taken which takes less than 10 seconds per eye.  Some times the eye is numbed with eye drops and probe is used to touch the eyes.  Because of the numbing eye drops one does not feel anything.  

The entire procedure takes not more than 10 minutes and lesser if done by an A scan in Mumbai.
