Corneal topography is an innovative method revealing 3D-surfaces of eye cornea. It’s designed to identify deformations, when the normal state is smooth. Corneal topographer allows physicians to keep eye diseases under control and structure surgical intervention.
Need for corneal topography
- Injuries sometimes leave scars. Topographic technique determines the degree of distortions.
- Growths. Size of pterygia or other neoplasms can also be kept under control thanks to such techniques.
- Keratoconus. You can identify the first signs of keratoconus and monitor its progress.
- Selection of lenses. It can reveal which lenses patients need. Special-designed hard lenses (RGP) are often needed.
Corneal topographer for operations
- Cornea is reshaped to rectify nearsightedness. Topography helps determine how to implement reshaping properly.
- If natural lenses become turbid, it’s changed replacing with IOL. Sometimes topography assists doctors in selection of appropriate IOLs.
- If corneal transplantation is done, physicians may turn to topography to heal and recover. Three-dimensional pictures identify which sutures need to be corrected.
- Operation of corneal crosslinking makes it possible to make the cornea stronger in case of keratoconus. It’s done to clarify whether surgeries are necessary. After the intervention, the cornea is scanned for observation.
The process of performing a topographic scanning of the cornea
- The patient should sit facing a special bowl. Chin remains securely to fix the head, guaranteeing most accurate picture.
- The patient needs to look at a stationary target when photographs are taken.
- Scanning process lasts just seconds; it’s carried out several times in a row.
Such procedure isn’t painful; it doesn’t irritate the eye in scanning.
Extended procedure
Medmont e300 corneal topographer – price is affordable on their official web) – is the best on the market. It is comfortable to use and has high accuracy. The device has a lot of great features that ensure functioning in the integrated Medmont Studio software. The E300 is a computerized video keratometer that uses Placido rings to map the cornea surfaces. Results of examination may be engaged for the choice of lenses and assessment of the general condition of the eye.
Exceptional corneal coverage
Using 32 rings with 9.6k measurement points and 102k analysis points, Medmont corneal topographer for sale provides clear topographic data over a large area of the human cornea. Coverage can be from 0.25mm to over 10mm, which is great for clear evaluation of corneal problems and perfect fit of lenses.
Automatic image capture and analysis
Best corneal topographers provide fully automated 3D image capture that makes patient examination easy and fast. Image capture occurs automatically, using a simple built-in alignment system. All you have to do is position the tool, guided by a fairly clear 3D focus target, and the software will begin to work.
All video frames are subject to analysis in terms of centering, focus and movement. The 4 best frames are automatically captured and developed in preview windows, further updated as more pictures are available, so the user can easily view and save the best frames for later analysis.
