This market includes Placido ring and Schiempflug camera topographers. The total market is expected to grow throughout the forecast. Most of the growth can be attributed to the growth in the Scheimpflug market. The market for Placido ring topographers will decline at a modest rate as their sales are being cannibalized by the competing technology: Schiempflug cameras. Despite the decrease in Placido ring topographer sales, this market is not expected to disappear. Although they do not provide as much information about the cornea as Schiempflug cameras, Placido ring topographers remain an excellent choice for eye care practitioners not involved in refractive surgery because the devices are sold at much lower prices.
The Schiempflug camera market will be limited by the device's high ASP compared to Placido ring topographers. Although the sales growth of Placido ring topographers are expected to decline, some demand will remain for these devices. Placido ring topographers have a low ASP relative to Schiempflug cameras and are suitable for purposes such as contact lens fitting. As a result, Placido ring topographers are sufficient for opticians and optometrists. Additionally, combination systems that include both Placido ring topographers and Schiempflug cameras are becoming popular. These systems take advantage of the strengths of each technology for corneal mapping. Schiempflug imaging excels at central corneal diagnostics whereas Placido ring analysis is better for peripheral corneal mapping. Thus, the combined systems are an enticing option for ophthalmologists who want to comprehensively analyze the cornea.
Corneal topography is also known as videokeratography or corneal mapping. Characterizing the curvature of the cornea is important because this tissue contributes significantly to the refractive power of the eye. Corneal topography is used for evaluating the curvature of the cornea. This information is then used for contact lens fitting and for planning refractive procedures such as Laser Assisted In-Situ Keratomileusis (LASIK) or Phakic intraocular lens implantation. Corneal topography is also used for detecting keratoconus, which is characterized by thinning of the cornea to a point where the intraocular pressure is sufficient to cause the cornea to assume a cone shape. The devices also have an application in planning cataract surgery.
Toric intraocular lens (IOL) implantation is effective in treating regular astigmatism. However, to the extent that the patient's astigmatism is irregular, with the principle meridians of the eye not lying perpendicular to one another, toric IOLs will be ineffective. Corneal topography can provide a definitive assessment of the nature of a patient's corneal astigmatism. As such, corneal topography is an essential preoperative step for the implantation of a toric IOL. Because of the increasing popularity of advanced technology IOLs in cataract surgery, and the associated importance of corneal analysis in the pre-operative process, manufacturers have been releasing products in recent years that specifically target applications associated with cataract surgery. This includes devices that combine corneal topography with optical biometry, pachymetry and other corneal measurements.
