A Study Comparing Intraoperative Aberrometry versus a Toric Calculator in Determining Toric IOL Cylinder Power and Axis
Recognizing the need for revolutionary and efficient technologies to enable regular eye exams, Smart Vision Labs launched its flagship product: the SVOne smartphone-based autorefractor powered by wavefront aberrometry.
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.
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.
Their breakthrough system ORange[R] is the first product available for intraoperative wavefront aberrometry registered by the FDA.
The SVOne uses wavefront aberrometry, a technology that measures refractive errors more comprehensively than common autorefractors.
Wavefront aberrometry shows promise for assessing and treating a wide range of challenging optical problems, such as cataracts, diabetic eye disease, and corneal refractive surgery.
The assessment includes intraocular pressure (IOP) measurement, fundoscopy, anterior eye segment examination, pachymetry, corneal topography, and aberrometry.
They give readers a strong background preoperative examinations, surface ablation procedures, LASIK and lens-based surgeries and cover such common complications as DLK and corneal infections, topographic and wavefront aberrometry disasters, femtosecond laser complications, post-LASIK ectasia, de-centered ablations and iatrogenic keratectasia, along with less-encountered conditions.
Wavefront custom cataract aberrometry with ORange is a breakthrough in modern cataract surgery.
