Biometry is a high-tech measurement method that analyzes the optical structure of the eye and calculates the personalized intraocular lens power in the most precise way. It is a mandatory preliminary test for choosing the right lens in smart lens (trifocal) and cataract surgeries.
Why is Biometry Done?
In smart lens surgeries, the same lens is not applied to every patient. Each eye's corneal curvature, axis length, anterior chamber depth and intraocular lens position are different. Biometry enables patient-specific lens selection by determining these values with millimetric accuracy.
What is Measured with Biometry?
- Anterior-posterior length of the eye (axis length)
- Corneal curvature (keratometry value)
- Anterior chamber depth
- Individual calculation of intraocular lens (IOL) power
How is Biometry Examination Done?
Biometry measurement is a painless, contactless and fast process. It is completed within seconds using optical scanning method, without touching the patient's eyes. The patient just looks at the device; The device analyzes the structure of the eye with the help of light waves. Current optical biometry devices such as IOL Master and Lenstar can make measurements with micron-level accuracy.
The Importance of Biometry Measurement
Biometry measurement is not just a preliminary test, but a critical step that directly affects the success of surgery. Incorrect or incomplete measurements may result in not achieving the desired visual clarity after surgery.
Frequently Asked Questions
Is biometry painful?
No. Biometry measurement is completely painless and contactless. The patient's eye is not touched; The device performs measurement with light waves.
When should biometry be done?
It should be done before cataract surgery or smart lens (trifocal) surgery is planned. Contact lens wearers should stop wearing lenses for a few days before measurement.
Which lens to choose with biometry?
In line with biometry data, the type of intraocular lens (monofocal, toric or trifocal) most suitable for the patient's age, profession and lifestyle is determined.
