The Sirius[R] corneal topography and aberrometry
system (6 mm pupil diameter, Costruzioni Strumenti Oftalmici, Italy) was used for corneal topography, dynamic infrared pupillography, ocular wavefront analysis and corneal wavefront analysis.
Holos Wavefront Aberrometry
provides cataract surgeons critical surgical information in real time, generating clear, continuous refractive data and assisting in the insertion and rotation of IOLs, titration of limbal relaxing incisions and opening of arcuate incisions.
A Study Comparing Intraoperative Aberrometry
versus a Toric Calculator in Determining Toric IOL Cylinder Power and Axis
In order to generate more accurate and reliable results, patients were instructed to stop using contact lenses for at least 02 weeks prior to aberrometry
The most commonly used apparatus is based on the principles of Hartmann-Shack aberrometry
, which measures distortions in a wave front of light emitted from the eye after it has passed through the eye's optics.
The SVOne device uses wavefront aberrometry
(an advanced technology used to characterize vision imperfection before performing corrective vision surgery) to measure a patient's refractive errors.
Multifocal laser treatments use the principle of ocular aberrometry
and aspheric laser ablation profiles to create a correction that is similar to those seen with centre-distance multifocal contact lenses.
The topics include highlights on statistics and clinical research, new operative tools to improve the structure, wavefront aberrations from A to Z, corneal aberrometry
changes following intra-corneal ring segment implantation, wavefront analysis and Scheimpflug imagery in the diagnosis of anterior lenticonus, and wavefront basic images.
In the 65 chapters, Garg, an ophthalmologist in India, and Alio (ophthalmology, Instituto Oftalmologico De Alicante, Spain) bring together ophthalmologists from across the globe to address complex cases and advanced topics in cataract surgery, ranging from biaxial and coaxial microincisional surgery to methods of manual small incision extracapsular surgery, as well as new technologies and approaches like using intraoperative wavefront aberrometry
and glue-fixating IOL haptics.
Among the topics are clinical biomechanics and the ocular response analyzer in ecstatic disease, pre-operative risk factors and medical and legal considerations of keratoectasia, studies of wavefront aberrometry
in corneal ectasia, non-surgical treatment using contact lenses, and corneal cross-linking with riboflavin and ultraviolet irradiation.
Clarity, which holds several patents in real-time intraoperative wavefront aberrometry
, said it is already planning upgrades to the HOLOS IntraOp platform.
