Cataract Surgery vs. LASIK: What You Need to Know

In New Zealand, cataracts are a leading cause of vision impairment, particularly among adults over 55. Additionally, around 35% of New Zealanders use some form of visual aid, such as glasses or contact lenses. 

Cataract surgery and LASIK are two advanced solutions that can improve vision and enhance quality of life. While the aim of both procedures is to enhance sight, they treat different issues; cataract surgery replaces a cloudy lens, and LASIK reshapes the cornea to correct refractive errors.

At re:vision, we’re leaders in laser and cataract surgery in Auckland. In this article, we explain the differences, benefits, and ideal candidates for each procedure, helping you choose the best option for your vision correction needs.

Key Takeaways:

• Cataract surgery replaces a cloudy lens, while LASIK reshapes the cornea.
• Cataract surgery is typically for older adults; LASIK is for those 18+.
• Both procedures are quick, with minimal downtime and high success rates.
• Cataract surgery is medically necessary, while LASIK is elective for improved vision.
• Consult with an eye specialist to determine the best option for your vision needs.

What is Cataract Surgery?

Cataracts arise when the eye’s natural lens becomes cloudy, leading to blurry vision, double vision, sensitivity to bright light, and difficulty seeing at night. Cataract surgery is a highly effective procedure designed to restore clear vision by removing the clouded lens and replacing it with an artificial intraocular lens (IOL).

Cataract removal can be most beneficial for older adults, as cataracts typically develop with age. Eye specialists often suggest cataract surgery when the clouding begins to severely affect daily activities. The cataract procedure is quick, usually taking less than 20 minutes, and has a great success rate. Post-surgery recovery is generally smooth, with most patients noticing clearer vision within a few days, and full improvement within a few weeks.

What is LASIK Surgery?

LASIK (Laser-Assisted In Situ Keratomileusis) is a popular laser eye surgery designed to treat common refractive errors such as nearsightedness, farsightedness, and astigmatism. It involves reshaping the cornea with a precise laser to help light properly focus on the retina, leading to clearer vision without glasses or contact lenses.

LASIK can be a great option for those looking to reduce their dependency on visual aids. The procedure is quick, usually taking less than 15 minutes per eye, and most patients experience enhanced vision within one or two days. This form of laser eye surgery has a high success rate and results in minimal downtime.

Key Differences Between Cataract Surgery and LASIK

To simplify things, you can explore a summary of the key differences between the two procedures below:

• Purpose: Cataract surgery treats vision impaired by cataracts, while LASIK corrects refractive errors.
  
  
• Age and candidates: Eye surgeons typically recommend cataract surgery for older adults, whereas LASIK is suitable for those aged 18 or over with stable vision prescriptions.
  
  
• Surgical technique: Cataract surgery involves replacing the cloudy lens with an artificial lens implant, while LASIK reshapes the cornea to focus light correctly on the retina. Anaesthetic eye drops effectively numb the eyes during both procedures, ensuring patients remain comfortable and experience minimal discomfort.
  
  
• Recovery: Both are an outpatient procedure, offering quick recovery times, with most patients returning to normal activities within 1-2 days.
  
  
• Medical necessity: An eye surgeon will perform cataract surgery out of medical necessity, as untreated cataracts can lead to significant vision loss. In contrast, LASIK is an elective procedure chosen to improve visual quality and reduce dependence on glasses or contact lenses.

Which Surgery is Right for You?

Both cataract surgery and LASIK are highly effective procedures that address different vision issues. The surgery that's right for you depends on the vision problems you're experiencing. If you have cataracts, surgery is essential to restore your vision and prevent further deterioration. For those with refractive errors, LASIK can help reduce the inconvenience associated with the reliance on visual aids. Sometimes, patients who've undergone cataract surgery may still require LASIK if they experience lingering refractive issues.

Consulting an eye specialist is the best way to explore your options and choose the surgery that best suits your needs, ensuring an excellent outcome and a significant enhancement in your everyday life.
