What is Laser Cataract Surgery?
Laser cataract surgery, also known as femtosecond laser-assisted cataract surgery (FLACS), is a minimally invasive procedure used to remove cataracts from the eye. Cataracts occur when the natural lens of the eye becomes cloudy, causing blurred vision and other visual problems.
During laser cataract surgery, a laser is used to create precise incisions in the cornea and lens capsule, which is the thin, clear membrane that surrounds the natural lens. The laser is also used to soften and break up the cataract into smaller pieces, which can be easily removed from the eye.
The benefits of laser cataract surgery over traditional cataract surgery include increased precision and accuracy in incisions, reduced energy required to remove the cataract, and faster recovery times. Laser cataract surgery is typically performed as an outpatient procedure and takes about 10-20 minutes per eye. It is generally considered safe and effective for most patients with cataracts.
The purpose of laser cataract surgery is to remove a cloudy, damaged natural lens from the eye and replace it with an artificial lens implant to restore clear vision. Cataracts are a common age-related eye condition that can cause blurry, dim, or distorted vision, and may interfere with daily activities such as driving or reading. Laser cataract surgery is a modern, advanced technique that can improve the accuracy and precision of the procedure, potentially leading to better visual outcomes for patients. Additionally, laser cataract surgery may offer faster recovery times and less discomfort compared to traditional cataract surgery. The ultimate goal of the procedure is to help patients see clearly and improve their quality of life.
Laser cataract surgery involves several steps, including:
- Eye preparation: Before the surgery, the patient’s eye is numbed with anesthetic drops, and the surgeon cleans and sterilizes the area around the eye.
- Creating incisions: A femtosecond laser is used to create precise incisions in the cornea and lens capsule, which are necessary to access and remove the cataract.
- Softening and breaking up the cataract: The laser is also used to soften and break up the cataract into smaller pieces. This process is known as “laser fragmentation” and it can help reduce the amount of energy required to remove the cataract.
- Removing the cataract: Once the cataract is fragmented, the surgeon uses a small instrument, such as a phacoemulsification probe, to suction out the cataract pieces.
- Implanting the artificial lens: After the cataract is removed, an artificial lens is implanted into the eye. The lens is usually inserted through the same incision used to remove the cataract.
- Closing the incision: The incision is closed with self-sealing corneal sutures or with the use of specialized medical glue.
- Post-operative care: After the surgery, the patient is monitored for a short period of time to ensure there are no complications. The patient will need to use eye drops to prevent infection and promote healing. Follow-up appointments will be scheduled to monitor the healing process and ensure optimal visual outcomes.
Advantages over Traditional or Manual?
Laser cataract surgery offers several advantages over traditional or manual cataract surgery, including:
- Increased precision: The use of a femtosecond laser allows for highly precise incisions, which can result in more predictable and accurate outcomes.
- Reduced energy requirements: The laser can also be used to soften and break up the cataract, reducing the amount of energy required to remove it from the eye. This can help reduce the risk of complications and speed up the recovery process.
- Improved safety: The laser can reduce the risk of complications such as capsular tears and other intraoperative complications.
- Faster recovery: Patients may experience faster visual recovery and have less discomfort compared to traditional cataract surgery.
- Customizable incisions: Laser cataract surgery can allow the surgeon to customize the size and shape of the incisions to match the patient’s specific needs, which can lead to better visual outcomes.
- Reduced dependence on surgical skill: Laser cataract surgery can reduce the dependence on surgical skill and experience, making the procedure more accessible to a wider range of surgeons.
- Potential for better refractive outcomes: Laser cataract surgery can also be used to correct other vision problems such as astigmatism or presbyopia, potentially leading to better refractive outcomes.
Like any surgical procedure, laser cataract surgery has some risks and potential complications. Some of the most common risks associated with laser cataract surgery include:
- Infection: Any time the eye is opened, there is a risk of infection. This risk can be reduced by using sterile techniques and medications.
- Inflammation: The eye may become inflamed following surgery, leading to redness, swelling, and discomfort.
- Bleeding: A small amount of bleeding may occur during the procedure, which can increase the risk of complications.
- Capsular tear: The laser can cause a tear or rupture in the lens capsule, which can make the surgery more difficult and increase the risk of complications.
- Corneal swelling: The cornea, the clear outer layer of the eye, may become swollen following surgery, which can lead to blurred vision and other problems.
- Vision problems: While laser cataract surgery is generally safe and effective, there is a risk of complications that can affect vision, such as refractive errors, halos, or decreased vision.
- Increased pressure in the eye: Laser cataract surgery can cause an increase in pressure within the eye, which can lead to glaucoma or other complications.
It is important to discuss the potential risks and benefits of laser cataract surgery with your eye surgeon to determine if it is the right choice for you.
How to Prepare
To prepare for laser cataract surgery, your eye doctor or surgeon will likely provide you with specific instructions. Here are some general tips to help you prepare:
- Arrange for transportation: Since you will not be able to drive immediately following the surgery, arrange for someone to drive you home after the procedure.
- Follow your doctor’s instructions: Your surgeon may provide specific instructions to prepare for the procedure, such as avoiding certain medications or foods before the surgery.
- Bring a list of medications: Bring a list of all current medications, including over-the-counter medications and supplements, to share with your doctor.
- Arrange for someone to assist you: You may need assistance with daily activities, such as cooking and cleaning, for a few days following the surgery.
- Stop smoking: If you smoke, it is recommended that you quit smoking for several weeks before and after the surgery, as smoking can delay healing and increase the risk of complications.
- Plan for recovery time: You may need to take time off work or other activities to allow for recovery time.
- Wear comfortable clothing: Wear comfortable clothing on the day of the surgery, and avoid wearing makeup or jewelry.
It is important to follow your doctor’s specific instructions to ensure the best possible outcome from the surgery.

How long has the procedure been performed?
Cataract surgery has been performed for thousands of years, dating back to ancient times when early surgeons used simple techniques such as couching, which involved pushing the cloudy lens out of the line of sight. Modern cataract surgery, which involves removing the cloudy lens and replacing it with an artificial lens implant, has been performed since the mid-20th century.
Laser-assisted cataract surgery is a more recent development, with the first FDA approval of a laser system for cataract surgery in 2010. Since then, laser cataract surgery has become increasingly popular due to its precision and accuracy, with more and more surgeons adopting this technique for their patients.
While traditional cataract surgery remains a safe and effective treatment for cataracts, the development of laser technology has improved surgical outcomes and reduced the risk of complications. Today, laser cataract surgery is widely available and has become the preferred method for many surgeons and patients.
How long does the procedure take
The duration of laser cataract surgery can vary depending on several factors, such as the severity of the cataract and the individual patient’s needs. However, on average, the actual laser portion of the procedure typically takes only a few minutes to complete.
The entire procedure, including preparation and recovery time, usually takes around 30 to 45 minutes. However, this can vary depending on the individual patient and the surgeon’s techniques.
It’s important to note that while laser cataract surgery is typically a fast and efficient procedure, the patient should plan to spend several hours at the surgical center for pre-operative preparations and post-operative recovery. After the procedure, the patient will be monitored for a short time in the recovery area and will need someone to drive them home.
Your surgeon will provide you with more specific information on what to expect during your procedure, including the estimated duration of the surgery.
Correcting Astigmatism During Laser Cataract Surgery
Laser cataract surgery can also be used to correct astigmatism, a common condition that causes blurred or distorted vision due to an irregularly shaped cornea or lens. Here are some ways that astigmatism can be corrected during laser cataract surgery:
- Limbal Relaxing Incisions (LRIs): LRIs are small incisions made at the edge of the cornea to help relax the cornea and correct astigmatism.
- Astigmatism-correcting intraocular lenses (IOLs): These specialized lenses are designed to correct both cataracts and astigmatism at the same time. They can improve vision without the need for eyeglasses or contact lenses.
- Toric IOLs: These IOLs are specifically designed to correct astigmatism. They are placed in the eye in a specific orientation to match the orientation of the astigmatism, allowing for clear and precise vision.
Your surgeon can help determine which option is best for your individual needs based on factors such as the severity of your astigmatism and your lifestyle needs. It’s important to discuss your options for astigmatism correction with your surgeon before your surgery to ensure the best possible outcome.
What is 3d imaging in laser cataract surgery?
3D imaging is a technology used in laser cataract surgery that provides a high-resolution, three-dimensional image of the eye. The 3D imaging system allows the surgeon to plan and perform the surgery with greater precision and accuracy.
During the imaging process, a device called an optical coherence tomography (OCT) scanner is used to capture detailed images of the eye. The OCT scanner uses a laser to take cross-sectional images of the eye, allowing the surgeon to see the exact location, size, and shape of the cataract, as well as the surrounding structures of the eye.
The 3D images created by the OCT scanner can be used to create a detailed surgical plan that is tailored to the individual patient’s needs. The surgeon can use the images to map out the location of the incisions, plan the size and shape of the capsulotomy, and select the appropriate IOL power and placement.
The use of 3D imaging in laser cataract surgery has several benefits, including:
- Improved accuracy: The high-resolution images provided by the 3D imaging system allow the surgeon to perform the surgery with greater accuracy and precision.
- Customized treatment: The detailed imaging allows for a customized treatment plan that is tailored to the unique needs of each patient.
- Enhanced safety: The precise planning and execution of the surgery can help reduce the risk of complications.
Overall, the use of 3D imaging in laser cataract surgery has revolutionized the field of cataract surgery, allowing for more accurate and precise treatment that can improve outcomes for patients.
The cost of laser cataract surgery can vary depending on several factors, including the surgeon’s experience, the location of the surgery, the type of lens implant used, and any pre-existing medical conditions that may affect the surgery. In the United States, the average cost of laser cataract surgery can range from $1500 to $2600 per eye, although this can vary significantly based on individual factors.
It is important to note that many insurance plans cover the cost of cataract surgery, although the specific coverage and out-of-pocket costs can vary depending on the plan. Some insurance plans may cover the cost of the basic cataract surgery procedure but not the cost of a premium lens implant, which may improve vision beyond what is achieved with a standard implant.
It is important to discuss the costs of laser cataract surgery with your surgeon and your insurance provider to determine the specific costs associated with your procedure and to understand your insurance coverage and any out-of-pocket expenses that may be required.
