What to Expect Before and After Implantable Collamer Lens Surgery

Before the implantable collamer lens surgery, an eye examination is done to assess the eye condition for the patient’s candidacy. After the surgery, all individuals experience that their vision gets better over time. Follow-up exams are recommended to make sure the eyes are healthy and the implantable collamer lens is well-fitted. People considering treatment at an implantable contact lens clinic should understand what to expect before and after the procedure to make informed decisions about their eye care.

Understanding Implantable Collamer Lens Surgery

An implantable collamer lens is a soft, foldable artificial lens that, when implanted inside the eye, corrects refractive problems such as myopia and astigmatism. And this is done by implanting the lens directly into the eye, rather than removing tissue from the eye as with laser treatment. An implantable collamer lens is a form of visual correction surgery that can sometimes be a quick alternative to laser procedures (Sanders et al., 2007).

Many patients who are referred to an implantable contact lens SG provider inquire about the thickness of their cornea or if their prescription is contraindicated for laser vision correction. An eye exam by an ophthalmologist is conducted to evaluate the candidate’s suitability.

Who May Be Suitable for the Procedure?

Patients who are not appropriate candidates for an implantable collamer lens still need to be clinically screened, as compatibility is made on various ocular criteria, and a low prescription alone is not a sole parameter to show suitability.

Factors commonly assessed include:

• Stable eyeglasses for a minimum of 1 year.

• Healthy cornea and retina.

• Sufficient anterior chamber depth.

• An adequate number of endothelial cells.

• No uncontrolled eye disease or active infection.

Patients who are considering the implantable contact lens in Singapore should know that this decision is made after examining the individual patient and that it is not necessarily the patient’s preference. The necessity for contact lens implantation should be discussed with an ophthalmologist to see whether other refractive surgeries in Singapore will be more suitable (Kamiya et al., 2018).

What Happens Before Surgery?

The first step in preparing for the procedure is obtaining measurements of the eye. These measurements involve the corneal curvature, the size of the pupil, the depth of the anterior chamber, the intraocular pressure, and the sizing of the lens. Imaging assists in the determination of the appropriate phakic intraocular lens and also decreases the complication rate from lens miscommunication.

The patient is generally instructed to cease use of lenses for a time period before the assessment, as the lenses may change the corneal shape temporarily. Medical history, current medications, and eye conditions are taken into account.

Summarised below is what patients can usually expect before surgery.

Stage	What happens
Initial Consultation	Medical review and running of vision assessment and goal setting.
Eye exam	Prescription, cornea, pupil, and anterior chamber measurement
Imaging	Lens size and a more detailed eye scan
Suitability review	Evaluation of the appropriateness of treating with an implantable contact lens in a clinic setting
Surgery planning	Discussion of the operation, recovery, and follow-up visits

Choosing an implantable contact lens clinic that performs detailed pre-operative assessment supports appropriate patient selection and treatment planning (Packer, 2016).

What Happens During the Procedure?

Implantable lens surgery is performed under local anaesthetic drops, which numb the eye. The surgeon then makes a tiny incision through which the folded phakic intraocular lens is introduced and positioned behind the iris and in front of the natural crystalline lens.

The operation itself normally lasts for a short period of time for each eye. However, the total time taken in the appointment may be somewhat longer to allow for the preparation time and post-operative observation. Most patients go home the same day after the ophthalmologist has checked the eye to confirm that it is stable.

Patients considering implantable contact lens SG are also instructed on the use of eye drops, protective spectacles, and follow-up visits before leaving the clinic (Alfonso et al., 2011).

Recovery After Surgery

Recovery will be different for everyone. For some, vision may start to be blurry on the first day and then start to clear up. Others can sometimes see clearly sooner, and for some, it may take a few days.

Following the vision correction surgery, there may be some temporary signs and symptoms. Mild pain, sensitivity to light, glare or halos and may ease with time during the healing process.

Patients are told not to rub their eyes, go swimming, or participate in strenuous activity until the early postoperative period has passed. The ophthalmologist will schedule follow-up appointments to check the healing process, intraocular pressure, and lens position.

Patients who have an implantable contact lens in Singapore should attend all scheduled reviews even if vision seems normal. This is because some complications are asymptomatic (Fernández-Vega-Cueto et al., 2018).

Long-Term Expectations

Most patients have stable vision following implantable collamer lens surgery if appropriately selected and followed. However, the eye is a dynamic organ, and routine eye examinations are still necessary.

Some people may end up needing prescription glasses (presbyopia is a normal ageing change and has nothing to do with the implanted lens).

When discussing the choices available with their implantable lens specialist, patients should inquire about how their vision should be affected, what risks may arise, the recommended follow-up appointments, and whether other procedures may be necessary. Patients thinking about having a refractive surgery in Singapore should be aware that every procedure is associated with both advantages and disadvantages, and recommendations are based on clinical findings and not personal preferences (Gell et al., 2014).

Conclusion

Knowing what to expect prior to and following implantable collamer lens surgery can make the process easier and help the patient relax, knowing what to expect. A consultation at an implantable contact lens clinic helps the ophthalmologist determine whether a procedure is appropriate by reviewing detailed measurements of the eye and eye health. With proper assessment, follow-up and managing a patient’s expectations, decision-making can be improved.
