Types of Cataract Surgery
Cataract surgery is a common and highly effective procedure to restore vision affected by cataracts. With advancements in medical technology, several surgical options are available, each with its benefits and considerations. This guide will explore the different types of cataract surgery, comparing their techniques, costs, and advancements, helping you make an informed decision about the best approach for your needs.
Cataract Surgery Techniques
Phacoemulsification
Phacoemulsification is the most common type of cataract surgery. This modern technique uses ultrasound waves to break up the cloudy lens into small fragments, which are then suctioned out. The minimally invasive procedure involves making a small incision, typically less than 3mm, which promotes faster healing and reduces the risk of complications. After the lens is removed, an intraocular lens (IOL) is implanted to restore vision. This technique allows for a quick recovery time.
Extracapsular Cataract Extraction (ECCE)
ECCE is a traditional method where a larger incision is made to remove the cataract in one piece. This technique is generally used when the cataract is too dense to be broken up by phacoemulsification. While it is effective for patients with certain eye conditions, there is also a higher risk of complications compared to the phacoemulsification technique, and also a longer recovery time.
An evolution of this method is called a small incision cataract surgery (SICS) which involves a slightly smaller incision and manual removal of the cataract. This procedure is suitable for dense cataracts and does not require ultrasound equipment, however, it requires a larger incision than the one performed in phacoemulsification, and it has a longer recovery time.
Intracapsular Cataract Extraction (ICCE)
ICCE is an older and less commonly used technique where both the lens and the surrounding capsule are removed through a large incision. This method is typically reserved for cases with significant trauma or other complications where other techniques are not feasible. It also has a higher risk of complications and longer recovery period, which is why it is not used very often.
Laser-Assisted Cataract Surgery
Laser-assisted cataract surgery is an advanced technique that uses a femtosecond laser to make precise incisions and soften the cataract for easier removal. This method enhances the accuracy of the procedure and can be used in combination with phacoemulsification. Its increased precision allows for potentially better visual outcomes compared to other methods.

Advanced Technology in Cataract Surgery
Advancements in cataract surgery technology have significantly improved the safety, precision, and outcomes of the procedure. Modern techniques and tools have transformed cataract surgery into one of the most successful and commonly performed surgeries worldwide.
uses a highly precise laser to perform several critical steps of the cataract surgery. The femtosecond laser creates corneal incisions, opens the capsule, and softens the lens for easier removal. This technology offers unparalleled accuracy and consistency compared to traditional manual methods. Benefits of FLACS include increased precision in creating corneal incisions and capsulotomies, reduced risk of complications, enhanced accuracy in lens positioning, and a shorter recovery time.
is an imaging technology that provides detailed cross-sectional images of the eye. OCT is used during laser-assisted cataract surgery to map the eye’s structure, allowing for customised surgical planning and more precise outcomes. Benefits of OCT include detailed visualisation of the eye’s anatomy, customised treatment plans based on individual eye characteristics, and improved accuracy in lens positioning.
is a technology used during cataract surgery to measure the eye’s refracture power after the cloudy lens has been removed. This real-time data helps surgeons select the most appropriate IOL power and ensure optimal placement, enhancing visual outcomes. Benefits of intraoperative aberrometry include real-time measurements during surgery, improved accuracy in selecting IOL power, and enhanced postoperative vision quality.
provide surgeons with a highly detailed, three-dimensional view of the surgical field. These systems enhance the surgeon’s ability to perform precise manoeuvres and make adjustments during the procedure. Benefits of 3D visualisation systems include, enhanced depth perception and spatial orientation, improved precision during surgery, and reduced strain on the surgeon, potentially improving performance.
incorporates robotic technology to assist surgeons in performing delicate parts of the procedure. These systems can increase precision and control, reducing the risk of human error. Benefits of robotic-assisted cataract surgery include, increased precision and control, reduced risk of complications, and enhanced consistency in surgical outcomes.
use advanced imaging techniques to assist surgeons in making precise incisions and placements during cataract surgery. These systems can overlay imaging data onto the surgical field, providing real-time guidance. Benefits of image-guided systems include, enhanced surgical precision, customised treatment plans, and improved visual outcomes.
uses short, high-frequency bursts of energy to perform cataract surgery. This method reduces the amount of heat generated, minimising tissue damage and improving recovery times. Benefits of MicroPulse technology include, reduced thermal damage to surrounding tissues, faster recovery, and enhanced safety and precision.
Cataract Surgery Costs and Options
The cost of cataract surgery can vary widely based on the type of procedure, the technology used, and the type of IOL implanted. Queensland Eye and Retina Specialists are a private ophthalmologist clinic and fee information will be discussed at the time of consultation.
Customising Your Surgery with Lens Options
Choosing the right intraocular lens (IOL) is crucial for optimising visual outcomes after cataract surgery. The lens you select can significantly impact your post-surgery vision quality and your overall satisfaction with the procedure.
These are the most commonly used lenses in cataract surgery. These lenses are designed to provide clear vision at a single focal point. Typically, they are set to focus on distance vision, which means that while you will have clear vision for activities like driving or watching television, you might still need glasses for near tasks such as reading or using a computer.
Benefits:
• Sharp distance vision
• Cost-effective
• Proven track record with high success rates
Considerations:
• You may still require glasses for near or intermediate vision tasks
These are designed to provide clear vision at multiple distances. These lenses have multiple zones with different focusing powers, allowing you to see clearly at near, intermediate, and far distances. This can significantly reduce your dependence on glasses for most daily activities.
Benefits:
• Improved vision at various distances
• Greater independence from glasses
• Suitable for active lifestyles
Considerations:
• Some patients may experience halos or glare around lights, especially at night
• Adaptation period may be required
These lenses are specifically designed to correct astigmatism, a common refractive error caused by an irregularly shaped cornea. These lenses have different powers in different meridians, which counteract the uneven curvature of the cornea, providing clearer vision.
Benefits:
• Corrects astigmatism
• Provides clearer vision at one or multiple distances, depending on the type of toric lens chosen
• Reduces the need for glasses or contact lenses for astigmatism
Considerations:
• Proper alignment of the lens is crucial for optimal results
• May be more expensive than standard monofocal lenses
EDOF IOLs are a newer type of lens designed to provide a continuous range of high-quality vision from distance to intermediate, with some improvement in near vision. These lenses extend the depth of focus, reducing the need for glasses, especially for intermediate vision tasks like working on a computer.
Benefits:
• Enhanced intermediate vision
• Reduced visual disturbances compared to multifocal IOLs
• Balanced performance for various activities
Considerations:
• Near vision might not be as sharp as with multifocal IOLs
• Slightly higher cost compared to standard monofocal lenses
Accommodative IOLs mimic the eye’s natural ability to change focus. These lenses shift position within the eye in response to the ciliary muscle’s movements, providing a range of vision from near to far.
Benefits:
• Natural focusing ability
• Reduced dependency on glasses
• Suitable for various vision tasks
Considerations:
• May not provide as extensive a range of vision as multifocal or EDOF IOLs
• Effectiveness can vary based on individual eye conditions
