Unlike laser-based vision correction surgeries like LASIK, LASEK, and SMILE LASIK, lens implant surgery preserves the cornea and lens, making it a highly safe procedure. Lens implant surgery can be broadly categorized into anterior chamber lens implantation and posterior chamber lens implantation. - Anterior chamber lens implantation involves inserting a lens in front of the iris, which is the toughest and most rigid tissue in the eye. The lens is directly fixed onto the iris. - Posterior chamber lens implantation involves inserting the lens behind the iris and in front of the crystalline lens.
In the case of anterior chamber lens implantation, the larger pupil allows for effective vision correction, and the risk of the lens rotating is minimal. However, a major drawback is that incision of the iris is required, which may compromise the overall stability of the procedure. On the other hand, ICL (Implantable Collamer Lens) posterior chamber lens implantation does not require iris incision, offering faster recovery and higher stability. This type of lens implant surgery can even be performed on the same day as the eye examination, making it a highly efficient and stable option.
ICL(Lens implant) surgery is typically considered for the following cases: - Patients with myopic regression or high risk of complications after LASIK or LASEK surgery. - Patients with high myopia (over -10 diopters). - Hyperopic patients. - Patients with thin corneas, making laser vision correction difficult. - Patients diagnosed with keratoconus. Additionally, even general myopia patients are increasingly considering lens implant surgery due to its fast recovery, lack of corneal damage, and the ability to achieve clear vision. However, ICL lens implantation can also have potential side effects in certain situations. One of the most critical factors is determining the appropriate lens size. If the lens is too small, it can scratch the crystalline lens and potentially lead to cataract formation. Conversely, if the lens is too large, it can obstruct the aqueous humor flow by pressing against the iris, leading to increased intraocular pressure and glaucoma. Additionally, if the lens is incorrectly positioned and does not align with the astigmatic axis, it can result in inaccurate vision correction, causing dizziness or residual astigmatism.
ICL Lens Implant Surgery requires accurate lens size selection and precise eye measurements to prevent serious complications like glaucoma and cataracts. To ensure satisfactory results, it is important to choose a surgeon with extensive experience in lens prescriptions and performing the procedure. Since the surgeon’s skill level can be difficult to assess for the average person, it can be helpful to check if the surgeon holds the ICL Reference Doctor Certification. This certification is awarded by the developer of ICL, STAAR, based on the surgeon’s surgical results and technical proficiency and is given to doctors with substantial clinical experience. Additionally, the ICL Young Ophthalmologist certification, awarded to the ophthalmologist with the most ICL surgeries performed among those under 45 years old, can also serve as an indicator of a surgeon's proficiency. These certifications can provide assurance of a surgeon's expertise, helping you make an informed decision.
