Optical Biometry

Optical Biometry is a highly precise, non-contact method of measuring the eye’s anatomical features using light-based technology. It plays a critical role in planning cataract and refractive surgeries, ensuring that the intraocular lens (IOL) implanted matches the patient’s exact visual needs.
Unlike older ultrasound-based methods, optical biometry uses laser or partial coherence interferometry to take precise measurements without touching the eye, making it more comfortable and accurate.

Uses

Measuring corneal curvature (keratometry)
Calculating the power of the intraocular lens (IOL) before cataract surgery
Measuring axial length (distance from the cornea to the retina)
Assessing anterior chamber depth and lens thickness
Detecting irregular eye shapes or conditions affecting surgery outcomes

Benefits & Advantages

No Contact with the Eye: Reduces the risk of infection and discomfort.
Highly Accurate Measurements: Essential for premium IOLs, toric lenses, and multifocal implants.
Quick & Painless: The process is completed in just a few minutes.
Better Surgical Outcomes: Helps achieve sharper vision and reduced dependency on glasses.
Ideal for Sensitive Eyes: Suitable for patients who may not tolerate traditional ultrasound methods well.
