# Glaucoma Treatment Market
Glaucoma is a group of diseases characterized by pathologically elevated intraocular pressure, leading to progressive optic nerve damage, which results in visual field defects and even permanent blindness.Glaucoma is the second leading cause of blindness worldwide.`, second only to cataracts, is also`The World's No. 1 Irreversible Blinding Eye Disease。According to FMI data,The net value of the glaucoma treatment market will increase from USD 5.5 billion in 2021 to$7.6 Billion in 2032, with an average annual compound growth rate of 3%.
Reducing intraocular pressure to decrease visual field progression is the only currently verified treatment for glaucoma.Methods for treating glaucoma include medication, laser treatment, and surgical treatment.Eye drops are a recognized treatment for glaucoma, but if medication does not adequately control intraocular pressure, doctors may consider laser treatment or minimally invasive glaucoma surgery (MIGS). In necessary cases, traditional invasive filtering surgery may also be required.
Traditional Glaucoma SurgeryMainly focusing on trabeculectomy and glaucoma drainage device implantation.External Drainage Surgery MethodBoth are non-physiological drainage methods, which involve artificially creating a long-term filtering bleb under the conjunctiva to directly drain aqueous humor from the anterior chamber into the bleb, thereby achieving the effect of lowering intraocular pressure. Theoretically, this surgical method results in the greatest reduction in intraocular pressure and has the widest range of application.
But the disadvantage is that once the filtering bleb is established, it requires lifelong maintenance, and there are many棘手complications during and after the surgery.Such as shallow anterior chamber, low intraocular pressure, endophthalmitis, and filtration bleb complications, etc. In addition, the filtration bleb may fail for various reasons at a later stage, leading to increased intraocular pressure.
# ViaLase Laser Femtosecond Laser System
ViaLase laser is designed to combine the precision of femtosecond laser technology with the accuracy of micron-level image guidance, providing a method calledFemtosecond Laser Image-Guided High-Precision Trabeculotomy or FLigHT Non-Invasive Glaucoma Treatment。
Different from other glaucoma surgeries,FLigHT does not require the creation of a fistula, thus potentially reducing the risk of associated complications.。

ViaLase® Laser Technology Developed by ViaLase, asThe First ProductFemtosecond Laser for the Treatment of Primary Open-Angle Glaucoma (POAG), which represents a major technological breakthrough in the field of ophthalmic treatment.
This technology throughNon-invasive, Non-surgicalMethod,Precise Operation Using Femtosecond Laser, providing a completely new solution for glaucoma treatment.This innovative approach may revolutionize existing treatment paradigms., improve the treatment outcomes and quality of life for patients.
Another product under ViaLase, Inc. ——ViaLuxe Laser System, used for performing femtosecond laser image-guided high-precision trabeculotomy (FLigHT). The surgery aims to utilize femtosecond laser and micron-level precise anterior chamber angle imaging technology,Creating a customized drainage channel non-invasively through the trabecular meshwork to reduce intraocular pressure.。
ViaLens Patient Interface: Provide a clear field of view in a non-invasive manner, and precisely deliver femtosecond laser to the trabecular meshwork;
ViaVue Gonioscope: Display the angular structure of all four quadrants, providing doctors with a comprehensive perspective;
ViaLuxe Laser: Precisely create channels, protecting adjacent tissues from damage;
ViaLink: Connect to a tablet via Bluetooth, allowing doctors to view program data and diagnostic information in real time;
Currently, according to the official website of ViaLase, Inc.,Neither of the two products has been launched for sale and they are still awaiting regulatory approval.。

# ViaLase Laser Clinical Data
In 2023, ViaLase, Inc. announced the 24-month human study safety data of the first FLigHT non-invasive glaucoma treatment using ViaLase technology.
During the 24-month observation period,The average intraocular pressure of patients decreased from 22.3±5.5 mmHg at baseline to 14.5±2.6 mmHg.A decrease of 34.6%。

In the same year, the results of ViaLase, Inc.'s Phase 1 VIA-001 trial showed that at all follow-up time points (1 month, 3 months, and 6 months post-operation),The average intraocular pressure decreased by 20%, 25%, and 23%.。
68% of the surgical eyes achieved ≥20% intraocular pressure reduction at 6 months without the need for additional glaucoma medications.。
At the 2023 American Glaucoma Society meeting, ViaLase also presented another 12-month study result.The results show that,The mean IOP was significantly lower after treatment, and none of the patients required IOP-lowering medications at 1 year., and no scars were found during the gonioscopy examination.
In October 2023, ViaLase announced the completion of patient enrollment in the Phase 2 VIA-002 trial.Phase 2 Trial to Compare ViaLase with Selective Laser Trabeculoplasty (SLT)
