Surgeon proposes keratoconus is caused by eye rubbing
Clinician and researcher Damien Gatinel, PhD, MD, strongly believes that keratoconus is caused by patients rubbing their eyes and sleeping with their faces against the pillow. Since 2007, he has headed the service for anterior segment and refractive surgeries at the Rothschild Foundation in Paris. He manages patients with refractive surgery, cataract surgery and keratoconus […]
Evaluation of total and corneal wavefront high order aberrations for the detection of forme fruste keratoconus.
Invest Ophthalmol Vis Sci. 2012 May 17;53(6):2978-92. doi: 10.1167/iovs.11-8803. Saad A., Gatinel D. Abstract PURPOSE: To investigate the application of anterior corneal and ocular aberrations in detecting mildly ectatic corneas. METHODS: This study retrospectively reviewed the data of 220 eyes separated into three groups by the NIDEK Corneal Navigator System automated corneal classification software: normal (N) (n = […]
Subclinical keratoconus: the need for an objective classification system.
Ophthalmology. 2013 Aug;120(8):e56-7. doi: 10.1016/j.ophtha.2013.04.028. Saad A, Gatinel D. Comment in Author reply: To PMID 22892148. [Ophthalmology. 2013] Comment on Use of a support vector machine for keratoconus and subclinical keratoconus detection by topographic and tomographic data. [Ophthalmology. 2012]
Corneal enantiomorphism in normal and keratoconic eyes.
J Refract Surg. 2014 Aug;30(8):542-7. doi: 10.3928/1081597X-20140711-07. By Saad A, Guilbert E, Gatinel D. Abstract PURPOSE: To evaluate the ability to discriminate between normal and keratoconic corneas by analyzing intereye corneal asymmetry parameters and defining a score of similarity that outlines the normal range of asymmetry between right and left eyes. METHODS: This prospective, non-randomized study included 102 normal […]
The mystery of collagen cross-linking when it comes to in vivo biomechanical measurements.
J Refract Surg. 2014 Nov;30(11):727. doi: 10.3928/1081597X-20141021-02. Gatinel D. Comment in Reply: To PMID 24972407. [J Refract Surg. 2014] Comment on Dynamic Scheimpflug-based assessment of keratoconus and the effects of corneal cross-linking. [J Refract Surg. 2014]
Repeatability of Keratometry Measurements Obtained With Three Topographers in Keratoconic and Normal Corneas.
J Refract Surg. 2016 Mar;32(3):187-92. doi: 10.3928/1081597X-20160113-01. By Guilbert E, Saad A, Elluard M, Grise-Dulac A, Rouger H, Gatinel D. Abstract PURPOSE: To assess the repeatability of the corneal topography functions of Orbscan II (Bausch & Lomb, Rochester, NY), OPD-Scan III (Nidek, Gamagori, Japan), and iTrace (Tracey Technologies, Houston, TX) in keratoconic eyes and in a control group of normal patients. METHODS: […]
Combining Placido and Corneal Wavefront Data for the Detection of Forme Fruste Keratoconus.
J Refract Surg. 2016 Aug 1;32(8):510-6. doi: 10.3928/1081597X-20160523-01. By Saad A. & Gatinel D. Abstract PURPOSE: To evaluate the accuracy of a new objective method based on Placido disk-derived data for the detection of eyes at risk of ectasia. METHODS: One hundred nineteen eyes of 176 patients were included and separated into two groups, normal and […]
Validation of an Objective Keratoconus Detection System Implemented in a Scheimpflug Tomographer and Comparison With Other Methods.
Cornea. 2017 Jun;36(6):689-695. doi: 10.1097/ICO.0000000000001194. Abstract PURPOSE: To validate a recently developed program for automatic and objective keratoconus detection (Keratoconus Assistant [KA]) by applying it to a new population and comparing it with other methods described in the literature. METHODS: KA uses machine learning and 25 Pentacam-derived parameters to classify eyes into subgroups, such as […]
The crosslinking controversy
I have just published a paper about in vivo corneal collagen cross-linking (CXL), and I believe it is certain to trigger some controversy. It is not my intention to be a heretic, but I truly believe that we should re-examine the in vivo benefits of the CXL procedure for keraoconus management. This illustration depicts the main lines of my […]
