Phakic Lens Surgery – Intraocular Lens ICL

What Is Phakic Intraocular ICL Lens Surgery and How Does It Work? Generally, Phakic Intraocular ICL Lens Surgery applies to patients with high prescriptions who cannot have standard laser vision correction. Specifically, this advanced procedure successfully treats severe myopia, hyperopia, and astigmatism eye defects simultaneously. Technically, the intraocular implant consists of a specialized collagen-based biocompatible material known as collamer. Importantly, Phakic Intraocular ICL Lens Surgery means that your surgeon leaves your natural lens completely untouched inside your eye. Consequently, this permanent lens works seamlessly with your existing anatomy to focus light properly onto your retinal surface.

Who Is Eligible for Phakic Intraocular ICL Lens Surgery?

Generally, patients between twenty-one and forty-five years old represent the ideal candidates for this advanced surgical treatment. Additionally, individuals whose eyes are not suitable for laser surgery due to thin corneas can choose this option. Fortunately, stable keratoconus patients over thirty-five years old achieve outstanding and permanent results through this micro-surgical method. However, Phakic Intraocular ICL Lens Surgery does not correct the progressive presbyopia reading vision problems that start after age forty-five. Therefore, older patients will still use standard reading glasses to view close-up objects clearly after their procedure.

Why Does Corneal Thickness Not Matter in This Advanced Procedure?

Specifically, your corneal thickness does not affect your candidacy for Phakic Intraocular ICL Lens Surgery at all. Conversely, standard refractive laser techniques strictly require a minimum corneal volume to reshape your eye tissue safely. Fortunately, the visual recovery after Phakic Intraocular ICL Lens Surgery remains remarkably fast, matching standard LASIK healing times. Furthermore, an experienced surgeon can safely remove or replace these implants in the future if your prescription changes. Additionally, the advanced built-in collamer technology permanently protects your delicate internal eye structures from harmful ultraviolet rays.

Understanding the Phakic Intraocular ICL Lens Surgery Process

Generally, Phakic Intraocular ICL Lens Surgery takes approximately twenty to thirty minutes of surgical time per eye. Subsequently, your medical team will closely monitor your progress in the clinical recovery room for a few hours. Fortunately, you can comfortably leave our hospital and return home on the exact same day of your procedure. Thereafter, you must apply antibiotic eye drops for one week and topical steroid drops for up to four weeks. Ultimately, patients must attend their mandatory follow-up appointments at one day, one month, and twelve months post-surgery.

Why Premium FDA-Approved STAAR Surgical Lenses Cost More

Clearly, our elite surgeons prefer utilizing FDA-approved EVO and EVO+ Visian lenses from the world-renowned manufacturer STAAR Surgical. Specifically, these biocompatible implants offer unmatched optical success rates for individuals with exceptionally high diopter refractive errors. Mali olarak, specialized ICL implants command a significantly higher price range than standard cataract intraocular lenses. Consequently, the overall treatment cost for Phakic Intraocular ICL Lens Surgery remains higher than traditional cataract procedures. Ultimately, investing in this premium clinical technology delivers absolute safety, maximum visual freedom, and a lifetime of clear vision.

How RLES AI supports phakic ICL planning

Our clinic uses RLES AI®, a clinical decision support system for refractive and lens surgery planning, as a second pass over the assessment before an implantable collamer lens is planned. A phakic lens leaves your own natural lens in place and adds an implant in front of it, so the questions are different from every other procedure on this site: the cornea is not reshaped, and the limiting factor is the amount of space inside the eye.

The single most misread number: anterior chamber depth

The space available for the implant is described by the anterior chamber depth, and the manufacturer’s indication defines it as the distance measured from the inner surface of the cornea (the endothelium) to the front of the natural lens. Devices do not all report that quantity. Some report the depth measured from the outer surface, which includes the corneal thickness and therefore reads roughly half a millimetre deeper than the value the indication asks for. Half a millimetre is larger than the entire margin between a suitable and an unsuitable eye.

The software therefore asks explicitly which surface the measurement was taken from. If it was taken from the outer surface, the corneal thickness is subtracted and the conversion is shown in the report. If the corneal thickness is not available, no conversion is performed and the value is recorded as missing rather than estimated — the one thing that must not happen here is a borderline eye being cleared by a number that was measured the wrong way.

Endothelial cell count is a preoperative number, and it matters afterwards

The implant sits close to the inner cell layer of the cornea, so the cell count is recorded before surgery and used as the baseline for follow-up. A ten-year series of 103 eyes with the current lens design found no cataract formation, no angle closure, no glaucoma and no lens removal over the decade, with 74 per cent of eyes within ±0.50 D of target and 99 per cent within ±1.00 D. Endothelial cell density and vault both declined slowly and predictably over the ten years — and the eyes that ended up as low outliers on cell count were the eyes that started with a lower count. That is the argument for measuring it properly before surgery rather than only after.

Vault, angle and pressure

Vault is the clearance between the implant and your natural lens: too little risks contact and cataract formation, too much crowds the drainage angle. It cannot be measured before surgery, only predicted from the eye’s own dimensions and then confirmed afterwards, so the report treats it as a prediction and names it as one. The anterior chamber angle value is read in every case, and the postoperative pressure follow-up schedule is written into the plan rather than left to routine.

Manufacturer indication limits are reported as they are

The age range, correction range and cylinder range are the manufacturer’s own indications, not our thresholds, and they are reported as such: the myopia indication covers a wider age band than the hyperopia one, and the hyperopic version carries a CE mark but is not FDA-approved — a regional distinction that the report states rather than glosses over.

The cornea is still screened, even though it is not being treated

A phakic lens does not remove corneal tissue, so it is sometimes offered as the answer for an eye that laser correction cannot serve. That is often correct — but it is only correct when the reason laser was excluded is tissue or optics, not disease. Where keratoconus or another ectatic condition is present, the shape of the cornea is still changing, and a lens implanted in front of a progressing cornea corrects a prescription that will not stay put. Ectasia screening and contact-lens-induced surface change are therefore run in full, and where the cornea is unstable the sequence is stabilisation first, at least 6 to 12 months of documented stability, and only then the refractive implant.

Why the record matters in a phakic eye

The decision is your surgeon’s. What the system adds is a record that each of these items was asked and measured — and, where a value was measured the wrong way or not at all, that this is stated instead of being quietly accepted. The software does not make a diagnosis, does not size the implant and does not guarantee an outcome. Detailed information: rlesai.com.
