What is Presbyopia?

  Presbyopia is a natural, age-related condition that affects the eye’s ability to focus on close objects. It typically begins to manifest in people over the age of 40 , and is a common part of the aging process. Unlike nearsightedness or farsightedness, which are due to the shape of the eye, presbyopia results from a gradual loss of flexibility in the eye’s natural lens. Here’s a detailed overview of presbyopia: What causes presbyopia? As we age, the crystalline lens inside the eye becomes thicker and less elastic. Additionally, the muscles surrounding the lens (the ciliary muscles) lose some of their strength. This combination makes it harder for the lens to change shape (a process called accommodation), which is necessary to focus light directly on the retina when looking at close objects. Symptoms of presbyopia: Difficulty reading small print, especially in low light. The need to hold reading material farther away to see it clearly (sometimes humorously called “...

What is Implantable Collamer Lens (ICL) Surgery?

  Implantable Collamer Lens (ICL) surgery is an advanced vision correction procedure designed to treat moderate to severe myopia (nearsightedness) , and in some cases astigmatism or hyperopia (farsightedness) . It offers an alternative to laser-based surgeries like LASIK and PRK , especially for patients who may not be ideal candidates for those procedures. Here’s a comprehensive look at ICL surgery: What is an Implantable Collamer Lens? An ICL is a soft, flexible, biocompatible lens made from Collamer® , a material that combines collagen and a polymer. This lens is implanted inside the eye, between the iris (the colored part of your eye) and the natural crystalline lens. It works with the eye’s natural lens to bend (refract) light properly onto the retina, thus correcting vision. How is ICL surgery performed? The procedure is minimally invasive and typically performed on an outpatient basis: A tiny incision (about 3 mm) is made at the edge of the cornea. The fol...

What is Refractive Lens Exchange (RLE)?

  Refractive Lens Exchange (RLE) , also known as Clear Lens Extraction (CLE) or Lens Replacement Surgery , is a surgical procedure designed to correct refractive errors such as presbyopia , severe hyperopia (farsightedness) , and in some cases myopia (nearsightedness) . This procedure is very similar to cataract surgery. However, instead of removing a cloudy lens (as in cataract cases), the natural clear crystalline lens of the eye is replaced with an artificial intraocular lens (IOL) to improve visual acuity. Here’s a detailed look at what RLE entails: Procedure: The surgeon removes the eye’s natural lens through a small incision and replaces it with an artificial lens implant (IOL). The type of IOL selected depends on the individual’s vision goals — options include monofocal, multifocal, and toric lenses. Candidates: RLE is typically recommended for individuals over 40 who are seeking a permanent solution to reduce or eliminate the need for reading glasses, bifocals, o...
