Disease relevance of Corneal Topography


High impact information on Corneal Topography

  • Patients were assessed using regular keratometry, corneal topography (TMS-1, simulated keratometry [SimK]), subjective refraction, and best-corrected visual acuity (VA) at each interval [6].
  • METHODS: Stability of the corneal topography pattern before surgical decision was observed for at least 6 months with the C-SCAN corneal topography with Ray Tracing (Technomed GmbH, Germany) and the Eye-Sys 2000 Corneal Analysis System (Eye Sys Co., Houston, TX) [7].
  • INTERVENTION: Videokeratography was performed with the TMS-2 and the CAS system 2000 [8].
  • Correlation of infrared pupillometers and CCD camera imaging from aberrometry and videokeratography for determining scotopic pupil size [9].
  • Intraocular pressure (IOP), pupil diameter, and corneal topography were measured before and 40 minutes after instillation of topical pilocarpine 4% or balanced salt solution [10].

Associations of Corneal Topography with chemical compounds


Gene context of Corneal Topography

  • It is, however, important to consider this association and obtain a corneal topography to rule out corneal ectasia in patients with HIES [20].
  • OBJECTIVE: To characterize corneal topography with INTACS (KeraVision, Inc., Fremont, CA) an ophthalmic device designed to correct myopia, and relate findings to visual performance [21].
  • Using a TMS-1 videokeratoscope, corneal topography was measured preoperatively and at 1 week and 1 and 3 months postoperatively [22].
  • Higher order optical aberrations were measured in 273 cyclopleged Singaporean school children using a Bausch and Lomb Zywave aberrometer, with 268 of these subjects also undergoing corneal topography measurements (Tomey TMS 2 system) [23].
  • PURPOSE: To study the parameters of corneal topography of normal eyes using the Corneal Analysis System (CAS, EyeSys Technologies) to determine the types and frequency of patterns and parameters [24].
