How common is intraocular lens dislocation?
Symptoms of Intraocular Lens Dislocation Intraocular lens dislocation is extremely rare. Occurrences of this complication range from . 2 to 3 percent of cases. Over the past decade, the risk of severe complications has continued to drop due to advances in surgical techniques and instruments.
What is a biometric eye test?
What is it? Biometry also known as A-scan ultrasound is widely used to measure the axial length of the eye for IOL power calculation. What is it done for? It is done for measuring the axial length of the eye in order to calculate the power of IOL lens to prior to cataract surgery.
Can a dislocated IOL be left untreated?
Untreated cases could develop severe decrease of visual acuity because of complete IOL dislocation in the vitreous chamber, chronic cystoid macular oedema (CME), anterior uveitis or retinal detachment.
What is Crystalens Z syndrome?
Z syndrome is an asymmetric vaulting of a plate-haptic IOL such as the Crystalens (Bausch + Lomb), in which one haptic is bent forward and the other is bent back due to asymmetric forces acting on the lens.
What is a monofocal?
The monofocal lens has one point of focus which is usually set for your distance vision but you would be blurred for near vision. In many cases, one eye can be set for a distance focus and the other eye for a near focus (so called “monovision”) to reduce the need for reading glasses.
What is the mode of action of Acrysof IQ?
MODE OF ACTION The AcrySof® IQ posterior chamber intraocular lens is intended to be positioned in the posterior chamber of the eye, replacing the natural crystalline lens. This position allows the lens to function as a refractive medium in the correction of aphakia.
What kind of material is the Acrysof IQ lens?
The AcrySof IQ lens (model SN60WF) is a single-piece IOL with proprietary blue light filtering chromophores that filter light in a manner that approximates the crystalline lens in the 400-475 nm blue light wavelength range. The lens is made from a high refractive index soft acrylic material that gently unfolds following implantation.
What kind of filter does Alcon IQ lens use?
The AcrySof® IQ lens with Alcon’s proprietary blue light filtering chromophore filters light…
What are the ND rates for Acrysof model sb30al?
AcrySof® Natural SINGLE-PIECE LENS Model SB30AL Nd:YAG RATES With a mean follow-up of 21.6 months, three (3) of the 135 subjects (2.2%) implanted with SB30AL experienced a Nd:YAG posterior capsulotomy. With a mean follow-up of 21.9 months, two (2) of the 127 subjects (1.6%) implanted with SA30AL experienced a Nd: YAG posterior capsulotomy.
