What is the purpose of this trial?

This trial aims to explore the effectiveness of wavefront-guided LASIK, a laser eye surgery, for individuals with presbyopia—a condition that makes close-up vision difficult with age. The treatment uses advanced laser technology to correct vision issues such as nearsightedness (difficulty seeing distant objects) and astigmatism (blurry vision due to an irregularly shaped cornea). It suits individuals over 40 who struggle with both distance and near vision, especially those who have been nearsighted for some time and require reading glasses. As an unphased trial, this study provides an opportunity to access cutting-edge technology that could significantly improve vision.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications that may affect healing, such as antimetabolites, isotretinoin, and amiodarone hydrochloride, within specific time frames before treatment. Additionally, if you are using inhaled or systemic corticosteroids, you are not eligible to participate.

What prior data suggests that this wavefront-guided LASIK is safe for presbyopia?

Research has shown that wavefront-guided LASIK is generally safe for patients. Studies have found that this type of LASIK surgery is well-tolerated, with a safety index of about 1.08, indicating it is very safe for correcting vision problems like nearsightedness.

However, some common side effects may occur. Patients might experience dry eyes or glare, especially at night. These effects usually improve over time. Anyone considering LASIK should discuss these potential side effects with their doctor to ensure the treatment is suitable for them. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike traditional treatments for presbyopia, like reading glasses or multifocal contact lenses, Wavefront-guided LASIK offers a surgical solution that could provide long-term vision correction. This treatment is unique because it uses the STAR S4 IR® Excimer laser System with iDesign Refractive Studio to customize the laser correction based on the unique wavefront of the eye, potentially improving both near and distance vision in one procedure. Researchers are excited because this approach could offer a more permanent and personalized solution for presbyopia, reducing the dependency on corrective lenses.

What evidence suggests that Wavefront-guided LASIK is effective for presbyopia?

Research has shown that wavefront-guided LASIK, the treatment under study in this trial, effectively improves vision. Studies have found that this type of LASIK often yields better results than other types. For instance, it can enhance clarity, with many achieving 20/16 vision, meaning they can see at 20 feet what someone with normal vision sees at 16 feet. Wavefront-guided LASIK also reduces issues like glare and halos more effectively. These positive outcomes suggest it could effectively treat presbyopia, the difficulty in seeing close objects as people age. ^{1 2 5 6 7}

Are You a Good Fit for This Trial?

This trial is for people over 40 with myopia and presbyopia who need at least +1.25 D to +2.00 D reading add power, have stable vision, and can follow the study's schedule. Pregnant women or those on certain medications affecting healing are excluded.

Inclusion Criteria

Require an add power of +1.25 D or more but not greater than +2.00 D at 40 cm

Your cornea has to be thick enough to safely perform the surgery, which means it needs to have a certain minimum thickness after taking into account the planned treatment depth.

A stable refractive error (based on a previous exam, medical records, lensometry, or prescription that is at least 12 months prior to the preoperative manifest refraction), as defined by a change of less than or equal to 0.50 D in MRSE (sphere and cylinder)

Exclusion Criteria

I cannot tolerate monovision correction as per a contact lens trial.

Subjects with a cardiac pacemaker, implanted defibrillator or other implanted electronic device

You have had a bad reaction or your body doesn't respond well to any of the medications used after surgery.

Published Research Related to This Trial

PresbyLASIK, a new treatment strategy using excimer lasers to create a multifocal cornea, shows promise as a potential solution for presbyopia, which currently lacks effective surgical options.

While initial clinical results are encouraging, further controlled studies are necessary to address unresolved questions regarding the safety and efficacy of this procedure.

[PresbyLASIK: treatment approaches with the excimer laser]. Becker, KA., Jaksche, A., Holz, FG.[2018]

LASIK surgery demonstrated good safety and efficacy in a presbyopic population aged 40 to 69, with 80% to 100% of eyes achieving 20/30 vision or better after the procedure.

While older patients showed a trend toward higher retreatment rates and slightly worse visual outcomes, there was no significant risk of visual loss, indicating that LASIK remains a viable option for this age group.

A novel customization algorithm used in LASIK surgery for presbyopia treatment significantly reduced higher order optical aberrations, leading to improved visual outcomes.

After six months, 78% of the 36 presbyopic subjects achieved 20/20 vision or better for near vision, with 92% for intermediate and 86% for distance vision, indicating the procedure's safety and efficacy.

A study of 92 patients showed that combining the PresbyMAX treatment in the nondominant eye with standard LASIK in the dominant eye effectively corrected both myopia and presbyopia, with all patients achieving 20/20 or better binocular vision at 6 months post-surgery.

The results indicate that this treatment is safe and effective, as 84% of dominant eyes achieved 20/16 vision, and all patients reached J2 or better for near vision, demonstrating significant improvements in both distance and near visual acuity.

In a study of 28 patients aged around 56 years, the novel bilateral presbyopic LASIK technique achieved 100% of patients having 20/20 or better distance vision at 6 months, significantly outperforming the 57% success rate of traditional monovision treatment.

The new LASIK method also provided better intermediate and near vision outcomes compared to monovision, with high patient satisfaction reported, indicating its effectiveness in treating presbyopic hyperopia.

A 72-year-old patient experienced improved near vision after undergoing Supracor LASIK for presbyopia and hyperopia, but faced significant side effects like glare and reduced distance vision due to treatment decentration.

The patient successfully underwent a reversal procedure using wavefront-guided treatment, which restored 20/25 distance vision and eliminated the dysphotopsia symptoms, marking a novel approach to correcting unsatisfactory outcomes from Supracor LASIK.

Six years after undergoing PresbyLASIK, patients showed excellent visual outcomes with a mean binocular uncorrected distance visual acuity of 20/18, indicating the procedure is both safe and effective for correcting presbyopia.

Postoperative assessments revealed stable corneal aberrations and improved near vision quality, with a notable 8% re-treatment rate, suggesting that while the procedure is effective, some patients may still require additional interventions for optimal satisfaction.

LASIK surgery for presbyopia showed good near vision improvement and high predictability, with 94% of patients achieving a refractive outcome within ±1.00 diopter, based on a review of 28 studies involving 15,861 eyes.

However, there was a noted decrease in distance vision efficacy and safety after the procedure, indicating that while LASIK can effectively improve near vision, it may compromise distance vision quality.

In a study of 277 patients undergoing simultaneous LASIK and Kamra corneal inlay implantation for hyperopic presbyopia, all age groups achieved a mean uncorrected distance visual acuity (UDVA) of 20/20, indicating the procedure is safe and effective across different ages.

Patients aged 60 to 65 (Group 3) experienced the greatest improvement in both UDVA and uncorrected near visual acuity (UNVA), along with the highest satisfaction levels, suggesting that age considerations can enhance postoperative outcomes.
