What is Laser cataract surgery?
The lens inside your eye that has become cloudy is removed using high frequency ultrasound device that breaks up the cloudy lens into small pieces, which are then gently removed from the eye with suction and replaced with an artificial lens to restore clear vision.
What is an Intraocular Lens (IOL)?
An Intraocular Lens (IOL) is an optical lens implant (artificial lens) made from synthetic materials such as silicone, acrylic, or plastic. An IOL is used to replace the natural lens in your eye during cataract surgery. As with contact lenses, IOLs are available in different powers. The power of the IOL is chosen specifically for each eye based on measurements taken by your doctor before the surgery.
Which Intraocular Lens is best?
Your cataract surgeon can help you decide which intraocular lens is best for you, based on your daily activities and which type of vision, near or distance focus, is required to complete those activities. Other factors to consider include pre-existing conditions such as astigmatism, glaucoma, macular degeneration, corneal disease, or other conditions which will need a specific type of lens.
How soon can I go home after cataract surgery?
After the cataract surgery is done, you will need to rest in the recovery area until the effects of the sedation or anaesthesia wear off. This generally takes about 30 minutes to an hour. You can go home after you receive post-operative instructions from the surgery counsellor on how to care for your eyes at home.
Can I wear my contact lenses right until the day of cataract surgery?
Contact lenses alter the shape of the corneal surface and may affect the preoperative measurements of the cornea that is required to determine the type of lens to be used during the cataract surgery. Depending on the type of contact lenses you wear (soft, hard or RGP), you will need to stop wearing them one to four weeks prior to your cataract surgery. The corneal surface will not return to normal if you wear your contact lens until the day of cataract surgery, which can result in inaccurate corneal measurements and a disappointing postoperative vision outcome.
Can I have cataract surgery after LASIK or other refractive surgery?
Yes, cataract surgery can be performed after LASIK or other refractive surgery which reshape the cornea to correct vision. However, the significant surgical alteration in the corneal shape would require additional calculations to determine the correct lens power for the lens implant used during the cataract surgery. Prior records of vision from exams immediately before and after the refractive surgery can help the cataract surgeon determine the best intraocular lens (IOL) power for optimal visual outcome after the cataract surgery.
Fact or Myth-Cataracts can be reversed without surgery
Cataracts cannot be reversed without surgery. A part of the natural aging process, cataracts are caused by the gradual build-up of protein in the eye’s lens. Presently, no medications or eye drops exist that can dissolve or remove a cataract and surgery is the only viable treatment option, during which the cataract is removed and an artificial lens that completely restores the vision is implanted.
Myth- Eye drops can prevent or dissolve cataract
Fact – Currently, surgery is the only effective treatment for cataract.
Types of Intraocular Lenses
Scleral Fixated IOLs (SFIOL) – Ideally, the lens is placed in the capsular cover (bag) of the lens using the support structure of the natural lens. However, there will always be instances where “in the bag” implantation isn’t possible, requiring that the IOL be sutured to the sclera with special permanent sutures. Trans-scleral suturing of Posterior Chamber IOL or Scleral Fixated Intraocular lens (SFIOL) is wellestablished and is a good option in patients with insufficient capsular support or zonular support, either as a primary or secondary implantation. The other options in these cases are Anterior Chamber IOLs and Iris Fixated IOLs. Each has its merits and demerits.
