Laser cataract surgery, additionally known as Refractive optical device-Assisted Cataract Surgery, is a complicated variety of cataract surgery that uses time unit optical device technology to bring a brand new level of exactitude and accuracy to specific steps in cataract surgery that historically are performed with hand-held surgical tools.
These steps include:
- The membrane incision
- The anterior capsulotomy
- Lens and cataract fragmentation
The other exactitude, accuracy, and duplicability of each of those steps, once performed with an optical device, doubtless will scale back certain risks and improve visual outcomes of cataract surgery.
The membrane incision
The first step in cataract surgery is creating associate degree incision within the tissue layer.
Optical coherence imaging helps your Dr Set up the situation and depth of incisions created throughout laser-assisted cataract procedures. Oct scans provide high-resolution and cross-sectional pictures to create the cataract surgery as precise as attainable.
In conventional cataract surgery, the Dr. uses a hand-held instrument with a metal or diamond blade to form associate degree incision within the space wherever the tissue layer meets the albuginea. This incision permits the Dr. to achieve access to the inside of the attention to interrupt up and take away the cataract, which may be an evaporation of the eye’s natural lens that’s placed right behind the pupil.
Next, the associate degree lens system (IOL) is inserted and constituted, to switch the cloudy natural lens. The membrane incision is formed in an individual approach; therefore, it’ll self-seal once the surgery is complete, with none would like for stitches. The goal is to form associate degree incision with a particular location, depth, and length, all told planes. With the Oct image and a time unit optical device, it may be performed precisely while not the variable of Dr Expertise.
This is necessary not just for accuracy; however, additionally for increasing the probability that the incision is self-sealing at the top of the procedure that reduces the danger of infection.
A thin, clear capsule encircles the eye’s natural lens. In cataract surgery, the front portion of the capsule is removed step known as an anterior capsulotomy. This alters the Dr. to achieve direct access to the cloudy lens.
The rest of the membrane that continues to be intact within the eye mustn’t be broken throughout cataract surgery. As a result of it should hold the unreal implant in situ for the remainder of the patient’s life.
In ancient cataract surgery, the Dr. creates a gap within the capsule with a tiny low needle, so uses that very same needle or a forceps to tear the capsule in a very circular fashion.
In optical device cataract surgery, the anterior capsulotomy is performed with a time unit optical device, just like the kind utilized in LASIK vision correction surgery. Studies have shown that capsulotomies performed with an optical device have more significant accuracy and duplicability.
Studies even have shown that optical device capsulotomies alter higher centring of the lens system, and IOL positioning may be vital to consider crucial final visual outcomes.
Lens and cataract fragmentation
After the capsulotomy, the Dr. currently has access to the cataract to get rid of it.
In ancient cataract surgery, the inaudible device that breaks up the cataract is inserted into the incision. Throughout this phacoemulsification procedure, the ultrasound energy will cause heat buildup within the incision, which typically will burn the incision and negatively have an effect on the visual outcome by truly causation astigmatism.
An incision burn additionally incorporates a higher probability of unseaworthy and typically needs multiple sutures to shut.
The laser, on the opposite hand, softens the cataract because it breaks it up. By breaking apart the cataract into smaller, softer items, less energy ought to be required to get rid of the cataract. Therefore there ought to be less probability of burning and distorting the incision.
Laser cataract surgery may additionally scale back the danger of capsule breakage, which will cause vision issues once the surgery.
The membrane is as skinny as plastic wrap, and it is vital that the portion that’s left within the attention once cataract surgery is unbroken, therefore it will hold the IOL within the correct position for clear, artless vision.
The reduced phacoemulsification energy needed in optical device cataract surgery may additionally create the procedure safer to the inner eye that reduces the possibility of certain complications, like a retinal detachment.
Astigmatism correction at the time of cataract surgery
To reduce the necessity for prescription eyeglasses or to read glasses once cataract surgery, it’s necessary that little or no astigmatism is a gift once implantation of presbyopia-correcting multifocal IOLs and accommodating IOLs.
Astigmatism typically is caused by the tissue layer being additional recreated in one meridian than others. (In different words, it’s formed somewhat like associate degree football game instead of a baseball).
To reduce astigmatism, tiny incisions may be placed within the outer boundary of the additional recreate meridian; because the incisions heal, this meridian flattens slightly to offer the tissue layer a rounder, additional symmetrical form.
This procedure is termed quiet libel incisions (LRI) or astigmatic surgical incision (AK). Surgeons will perform LRI or Last Frontier manually with a diamond blade, and it’s quite effective in reducing astigmatism.
During refractive laser-assisted cataract surgery, the Oct image may be wont to set up optical device LRI or Last Frontier incisions during a} exact location, length, and depth. This will increase the accuracy of the astigmatism-reducing procedure and also the chance of excellent vision while not glasses once cataract surgery.
Laser cataract surgery systems
Examples of optical device cataract surgery systems include:

- LenSx system (Alcon) is approved for membrane incisions, capsulotomies, and lens (cataract) fragmentation.
- LensARThe optical device System (LensAR, Inc.) is approved for membrane incisions, capsulotomies, and lens (cataract) fragmentation. The “AR” represent “Augmented Reality,” which refers to proprietary imaging technology that collects associate degree new spectrum of biometric information, so reconstructs a complicated 3D model of the anatomy of every patient’s eye, in step with the corporate.
- Victus the time unit optical device Platform (Bausch + Lomb) is also approved for membrane incisions, capsulotomy and lens fragmentation in optical device cataract surgery. The Victus system options proprietary advanced arrival Technology that minimizes the chance of eye tilt or distortion and allows precise alignment designed to take care of the shape of the attention throughout laser-assisted cataract surgery, in step with the corporate.
- Femto LDV time unit optical device system (Ziemer Ophthalmic) offers a higher repetition rate of the shaft of light for quicker procedures, low energy per optical device pulse for gentler treatments, and overlapping optical device spots for prime exactitude and certainty, in step with the corporate.
All of those systems for optical device cataract surgery have shown excellent outcomes in clinical trials. The optical device your Dr. has chosen for his or her follow may be a matter of private preference, supported specific options, and different factors.
Typically, the talent of your Dr. is additional necessary than the complete optical device used for the laser-assisted steps of your cataract procedure.
Cataract surgeons UN agency use lasers say that their benefits square measure particularly evident once it involves sophisticated, premium implants like presbyopia-correcting multifocal IOLs and accommodating IOLs. Benefits embody higher lens placement and so additional correct visual outcomes.
Cost of optical device cataract surgery
Laser cataract surgery typically prices quite a conventional cataract surgery. Also, the further prices related to optical device cataract surgery generally don’t seem to be lined by medical or insurance.
Fees for optical device cataract surgery will vary considerably from one cataract Dr. to a different. Make sure to rise regarding details of the price of laser-assisted cataract surgery throughout your pre-surgical test and cataract surgery consultation together with your Doctor.
Weighing the advantages
It’s essential to place optical device cataract surgery technology into the correct perspective.
Traditional cataract surgery is beneficial and fruitful. Most of the people UN agency don’t need to pay the additional price of optical device cataract surgery will feel assured that conventional cataract surgery is probably going to provide superb results.
But if you wish the most effective attainable technology, optical device cataract surgery is appealing. An additional correct membrane incision, capsulotomy, and astigmatic correction could assist you to attain your goal of less dependence on glasses once cataract surgery.
