With the advancement of science and technology, new ophthalmic surgical techniques have emerged one after another, among which the most popular one is the phakic implantation surgery (PIOL). The goal of this surgery is to correct vision by implanting a special artificial lens and improve the quality of vision in patients with high refractive errors without removing the patient's natural lens. It is particularly suitable for patients for whom traditional corrective laser surgery, such as LASIK or PRK, is not appropriate.
Lenticular implantation can improve high myopia by up to −20 diopters.
The primary advantage of PIOLs is their suitability for treating a wider range of refractive errors that cannot usually be safely and effectively corrected with traditional corneal surgery. The technical requirements for this surgery are similar to those for cataract surgery, but the equipment required is less expensive. Best of all, PIOLs are removable, and even if other eye surgery is needed in the future, it is possible to reverse their visual effects.
Compared to other refractive surgeries such as cataract surgery, lens implantation better preserves natural accommodation and reduces the risk of postoperative retinal detachment.
Before undergoing lens implantation, patients need to undergo a detailed preoperative evaluation. This includes measuring the anterior chamber depth, which is necessary to determine if surgery is appropriate. During the operation, the doctor will use special instruments to implant the lens into the eye, and will prescribe antibiotic eye drops to the patient after the operation to prevent post-operative infection.
Regular follow-up after surgery is essential to ensure the success of the surgery.
Although lens implantation has many advantages, there are still some potential risks and complications. These include postoperative glare and halos, and night vision may be affected, especially in patients with large pupil diameters. Additionally, the implanted lens may cause a shallow anterior chamber, which may lead to blurred vision or cataracts in the long term.
While lens implantation is effective for many patients, not everyone is a candidate for this surgery. This procedure is not recommended for patients under 21 years of age, those with unstable refraction, or those with a history of eye disease. In addition, the risk of implantation is greatly increased in patients with a shallow anterior chamber.
ConclusionCompared to cataract surgery, the risk-benefit balance of lens implantation is relatively low.
In the pursuit of better vision, lens implantation provides patients with another effective option. However, the effectiveness of surgery and its risks are also issues that deserve in-depth consideration by every patient considering surgery. If you were facing vision problems, would you choose the treatment option that was best for you?
