Laser eye surgery techniques continue to develop, with ongoing advances in corneal reshaping and surgical imaging. These procedures are used to address refractive errors, while some laser systems are used in specific steps of cataract surgery. Imaging technologies can provide real-time views of eye structures to help surgeons navigate and perform procedures. Here is more information on the latest innovations in laser eye surgery techniques:
LASIK Technology
LASIK is a laser eye surgery that corrects nearsightedness, farsightedness, and astigmatism by reshaping the cornea to improve how light focuses on the retina. During the procedure, a surgeon creates a thin flap in the cornea and uses a computer-guided laser to reshape the underlying tissue according to the patient’s prescription. They then reposition the flap so it heals naturally. A comprehensive eye examination determines whether LASIK is appropriate based on several factors, including:
- Age
- Lifestyle and vision needs
- Overall eye health
- History of eye surgery
- Corneal thickness
- Prescription strength and stability
Three-Dimensional Surgical Visualization
Three-dimensional visualization technology provides eye surgeons with a detailed view of the surgical field during delicate procedures. By displaying magnified images on a monitor, the technology allows surgeons to observe surgical anatomy without relying exclusively on microscope eyepieces. This approach supports visualization and procedural guidance while leaving clinical judgment and surgical execution in the hands of the surgeon.
During cataract surgery, image-guidance technology can assist with incision placement and toric intraocular lens alignment. Capsulorhexis, the creation of a circular opening in the thin capsule surrounding the natural lens, is a key step that enables removal of the cloudy lens. For patients with astigmatism, toric intraocular lenses provide targeted correction, making accurate alignment a key factor in achieving the intended visual outcome.
Beyond the surgical field, three-dimensional visualization can facilitate communication among members of the surgical team by providing a shared view of the procedure. The technology also supports patient education by helping clinicians illustrate surgical techniques and explain treatment options. These visual resources help improve patients’ understanding of the procedure and help them make informed decisions about their care.
Alternative Vision Correction Techniques
Photorefractive keratectomy (PRK) uses a laser to reshape the cornea and improve light focusing in the eye. PRK is an alternative to LASIK for some patients with thinner corneas. EVO Implantable Collamer Lens (EVO ICL) corrects refractive errors with a lens implanted inside the eye; refractive lens exchange replaces the natural lens with an artificial one. Small corneal implants provide structural support for the cornea in patients with keratoconus.
Femtosecond Laser Technology
Femtosecond lasers deliver ultrashort pulses of light during certain eye surgeries. In LASIK, the laser creates a thin flap in the cornea, the clear front surface of the eye. A second laser reshapes the cornea to correct refractive errors, including nearsightedness.
Femtosecond lasers also assist with specific steps of cataract surgery. The laser creates small incisions in the cornea and fragments the cloudy natural lens before removal, and then the surgeon removes the lens fragments from the eye. An artificial lens is implanted to replace the natural lens and improve vision. The surgical approach depends on the patient’s eye condition and the procedure being performed.
Explore Laser Eye Surgery Options
Laser eye surgery includes procedures for correcting refractive errors and treating cataracts. LASIK and PRK reshape the cornea to correct vision problems, while laser-assisted cataract surgery involves steps to remove the cloudy natural lens. Each procedure uses a different technique and addresses specific eye conditions. An eye examination evaluates vision and overall eye health, and the results help determine which procedures are appropriate based on the patient’s eye condition and visual needs. Speak with an eye care professional about the available vision correction options.
