Unique in Romania: corneal investigations with the OCT MS-39 device

The new Schwind MS-39 is unique in Romania, capable of performing complex and detailed corneal investigations required for laser refractive surgery and accurate keratoconus diagnosis.

What you need to know about MS-39 investigations

The MS-39 is a high-performance OCT and topographer that provides a superior level of corneal detail and analysis. HD images provide more detail, excellent resolution and reveal the structure of the cornea down to the last detail.

We can then make the best possible treatment decisions, and rule out certain diagnoses, with the help of this multidisciplinary device. It is mainly used in cases of refractive surgery, suspected keratoconus, glaucoma, lens implants and even dry eye syndrome.

With MS-39, epithelial and stromal tissue can be examined separately from each other – particularly useful prior to transepithelial treatments or during keratoconus screening or postoperative lenticule evaluation. High-resolution sections also allow more accurate analysis of the depth of corneal opacities and assessment of corneal surface abnormalities.

In addition to high-resolution cross-sectional images of the cornea, the MS-39 also provides imaging details of the iridocorneal angle, iris and lens. This allows for an informed diagnosis that is individually tailored to the patient and makes laser treatment even safer.

Together with topography and Pentacam AXL Wave investigations, MS-39 investigations complete the cycle of pre-operative analysis and investigation in very delicate cases with “borderline” measurements, which until now were often risky for laser surgery and patients were advised to choose another surgical method.

We can today make a very delicate selection of these cases and avoid cases with potential corneal risks.

What do MS-39 investigations involve?

The MS-39 is the most advanced device for anterior segment eye analysis. The MS-39 combines Placido disc corneal topography with high-resolution OCT-based anterior segment CT scan.

The patient is instilled with drops to dilate the pupil and then placed with the chin on the special holder of the MS-39. This produces high clarity, cross-sectional HD images 16 mm in diameter, along with the many details of corneal structure and layers revealed by the MS-39.

What disorders can be diagnosed with MS-39?

MS-39 provides information on pachymetry, elevation, curvature and dioptric power of both corneal surfaces. In addition to clinical diagnosis of the anterior segment, MS-39 can be used in corneal surgery for planning refractive surgery. An IOL calculation module is also available, based on Ray-Tracing techniques. Additional tools allow MS-39 to perform precise pupillography measurements and advanced tear film analysis.

MS-39 is used to diagnose certain disorders and to support informed decisions related to IOL and refractive surgery:

  • Screening for keratoconus
  • Calculation module for intraocular lenses for planning the treatment of treated or untreated eyes with refraction.
  • Glaucoma diagnosis and monitoring
  • Planning and performing most refractive operations.
  • Diagnosis of “dry eye” syndrome

Benefits of the MS-39

  • Cross-sectional images with an extremely large diameter of up to 16 millimeters can be displayed for the entire anterior segment of the eye.
  • Highly detailed measurement of the corneal structure in all its layers
  • High-precision pachymetry and elevation information, curvature and dioptric power, each in relation to the surface of the anterior and posterior cornea
  • Greater diagnosis certainty due to in-depth information about the epithelium
  • Highly accurate representation of the epithelial map, with a resolution of 3.6 micrometers thanks to spectral domain technology
  • Excellent image quality for the anterior segment of the eye up to 16 millimeters in diameter
  • The MS-39 allows a highly detailed overview of the cornea, including corneal aberrations.
  • Screening for keratoconus – provides important data on the cornea and can make a preoperative contribution for avoiding possible complications associated with ectasia.
  • The calculation module for intraocular lenses, based on ray-tracing technology, is excellent for planning the treatment of treated or untreated eyes with refraction.
  • The placement of intrastromal rings can be precisely planned using pachymetry maps and a corneal elevation profile.
  • Glaucoma screening used in the diagnosis and monitoring of glaucoma
  • The built-in function captures pupil diameter dynamically or statically, depending on the defined lighting conditions. Accurate pupil center and pupil diameter data are essential for planning and performing most refractive treatments.
  • Lens biometry – Lens thickness and lens position in the eye can be accurately determined to support IOL calculation refinement
  • Dry eye analysis – Placido technology allows analysis of the tear film condition. This information provides support in diagnosing the symptoms of “dry eye”.

We constantly strive to offer patients the most modern surgical and diagnosis equipment and services, so that the decision and recommendation of a surgical solution comes after an extensive investigation process that takes into account all possible risks.
