The IOL implantation requires experienced and highly skilled medical staff.
We have 17 years of continued surgical experience since the opening of GS Eye Center.

The IOL implantation refers to a surgical procedure of inserting the intraocular lens into the eye. It requires high professionalism and skilled experience of the medical staff than other laser vision correction surgery. From anterior chamber lens implantation to posterior chamber lens implantation, such as GLAZE and EVO + ICL, the medical staff of GS Eye Center, with more than 17 years of experience, will guarantee the best outcomes.

Adherence to FDA guidelines; Safe surgery is possible without damaging structures in the eye.

The IOL implantation requires the process of inserting and unfolding the IOL folded under the dilated pupil. It is critical to have the skilled experience of inserting the IOL in the correct position at once so that it is not misplaced or overturned.

According to the standards *ICL type 3.0 mm or more / ARTISAN and ARTIFLEX 3.2 mm recommended by the US FDA, we can perform safe surgery by checking the ocular anterior chamber depth and the number of corneal endothelial cells without damaging the structures in the eyes.

  • Corneal endothelial cell count

    (Normal corneal endothelial cells: 2,000~3,000 ea.)

    The normal number of endothelial cells is 2,000~3,000, which do not regenerate once get damaged. Therefore, surgery is performed based on individual test results following the US FDA's safety standards.

  • Anterior chamber depth of the eye

    (AC-IOL 3.2 mm or more / PC-IOL 3.0 mm or more)

    The anterior chamber depth of the eye refers to the distance between the lens and the back of the cornea. The US FDA provides safety standards for the anterior chamber depth of the eye for safe IOL implantation.

A detailed examination minimizes the size error of the ocular space for IOL insertion, and the surgery is performed considering the actual size inside the eye and visual axis.

As IOL implantation is a delicate surgery requiring advanced technology, post-surgery care must also be done thoroughly. Even in surgery conducted after thorough diagnostic examinations, various unexpected situations may occur. Problems may arise when the IOL is rotated by rubbing eyes after surgery or when it is not properly taken care of by skipping regular check-ups. It is important to visit the clinic regularly for check-ups.

The anterior and posterior axial length of the cornea, corneal curvature, depth of anterior chamber, and white to white are measured by the state-of-the-art anterior segment imaging and diopter calculating devices for accurate calculations that are free of errors so that the ocular space is calculated in advance to choose the right IOL.

Triple Diagnostic Systems

Surgery is determined after passing the strict triple diagnostic systems.

  • K5M

    Diagnostic tester for dry eye

1. GLAZE

Optiflex GLAZE performed for the first time in Korea

Optiflex GLAZE is a PC-IOL implanted between the iris and the lens that allows for smooth drainage of aqueous humor through the center hole, eliminating the need for iridectomy. It is a premium IOL that provides clearer vision quality by being manufactured in an aspherical shape whose refractive index of light is scientifically calculated.

  • Clear vision

  • Proper flow of aqueous humor

  • Minimum incision surgery

Clear vision

Proper flow of aqueous humor

Minimum incision surgery

  1. Step.0101

    The human cornea is aspherical rather than spherical, so the aspherical lens made according to the refractive index of light is used in the surgery. It is thinner than a spherical lens and provides wide and clear vision without color dispersion or distortion of the field of view.

  2. Step.0202

    In most cases, you will experience improved vision the day after surgery. Quick recovery of a day or two is an advantage. There is almost no occurrence of xerophthalmia, and the post-surgery discomfort is also minimized.

    • GLAZE surgery: Aspherical lens

    • Conventional surgery: Regular spherical lens

  3. Step.0303

    The center hole, the pathway of intraocular aqueous humor, is created in a conical shape, which promotes the smooth flow of aqueous humor and lowers the incidence of cataracts and glaucoma. With five holes in total, the aqueous humor can be sufficiently drained without iridectomy.

    • GLAZE flow of aqueous humor

    • 5 Holes in total

    • Center hole (pathway of intraocular aqueous humor)

  4. Step.0404

    A minimum 2.8 mm incision during surgery minimizes tissue damage to enable fast recovery. It also reduces the risk of astigmatism and post-surgery discomfort.

  5. Step.0505

    Permanent vision correction is possible without cleaning or any maintenance process after surgery. You can restore your eye to its original state by removing the IOL if necessary.

2. EVO + AQUA ICL

ICL lenses are made of a material called Collamer, a polymer of collagen and HEMA.
Containing a small amount of purified collagen, it is the most human-friendly material that is optically very stable and effective.

  • Stability verification

  • Proper flow of aqueous humor

  • High satisfaction in surgery

Stability verification

Proper flow of aqueous humor

High satisfaction in surgery

  1. Step.0101

    The stability has been verified with 900,000 cases of surgeries over 20 years.
    The Collamer material, developed by STAAR Surgical Company for the first time globally and approved by US FDA, delivers stability.

    • Conventional IOL

      Protein deposition is confirmed when magnifying by 1,000 times after exposing it to a protein mixture for a minute.

    • EVO + AQUA ICL Lens

      Protein deposition is not detected in the same experiment.

  2. Step.0202

    The flow of aqueous humor is appropriate by creating the center hole and surrounding holes, which restores the natural flow of aqueous humor, reducing the possibility of developing cataracts and glaucoma.

  3. Step.0303

    99% post-surgery customer satisfaction! The stability and efficacy of ICLs have been proven through a number of studies over a long period of time, showing 99% of customer satisfaction.

    • I am satisfied with surgery.

    • I will choose ICL if I receive surgery again.

    • I am satisfied with the excellent visual acuity after surgery.

AC-IOL

3. Artiflex

The design of the lens was inspired by the claw shape of a lobster to stably fix the lens on the iris to correct vision.
Unlike ICL, it is securely fixed on the iris between the cornea and the lens. It does not contact the lens and cornea directly, thus reducing the possibility of developing cataracts and glaucoma.

  1. 01

    The recovery is quick enough to allow you to resume normal daily life and feel the corrected vision within 3 days after surgery.

  2. 02

    The IOL replacement is possible if your eyes get worse after surgery, and the IOL can be removed, if necessary, allowing reoperation at any time.

Regular check-ups every 6 months as post-surgery management is crucial for IOL implantation.
