OPHTHALMOLOGY BIOSIMILARS MARKET TRENDS

Rising Adoption of Cost-effective Biosimilars for Long-term Retinal Disease Management is a Prominent Trend Observed  

As healthcare systems seek to reduce the cost of managing chronic retinal diseases, increasing adoption of such biosimilars emerges as a major global market trend. Conditions such as wet age-related macular degeneration and diabetic macular edema often require repeated anti-VEGF biosimilars, creating a considerable long-term treatment burden for patients and payers. Biosimilars offer comparable clinical effectiveness and safety to their reference biologics while increasing competition and potentially lowering treatment costs. This is encouraging public healthcare providers to include biosimilar products in formularies and reimbursement pathways. Wider availability of cost-effective ranibizumab and aflibercept biosimilars can therefore improve treatment continuity and expand access among patients requiring prolonged therapy, supporting global ophthalmology biosimilars market growth.

• In September 2025, Biocon Biologics announced that YESAFILI, its aflibercept biosimilar, had received public funding under the Ontario Drug Benefit Formulary in Canada for treating retinal diseases. The reimbursement expanded patient access to a lower-cost alternative to the reference aflibercept product, demonstrating the growing integration of biosimilars into publicly funded long-term retinal care.

Rapid Aflibercept Biosimilar Conversion to Accelerate Market Growth

The rapid conversion of patients from reference aflibercept to biosimilar alternatives is expected to be a key factor driving market growth. Aflibercept is widely used for chronic retinal diseases and requires repeated intravitreal injections, resulting in considerable treatment expenditure for hospitals and public healthcare systems. Following the entry of approved biosimilars, payers and hospital networks are introducing structured conversion programs for existing patients while recommending biosimilars for newly initiated patients. These programs can generate substantial demand within a short period, as large established patient populations are moved from the reference product rather than relying only on newly diagnosed cases. Wider formulary inclusion, procurement contracts, and physician familiarity with biosimilar switching are therefore expected to accelerate product uptake and encourage additional manufacturers to enter the market.

• After December 2025, the King’s College Hospital NHS Foundation Trust began switching ophthalmology patients from reference Eylea to Vgenfli, an aflibercept biosimilar, as part of a national best-value medicines initiative. The hospital stated that the change would apply to patients receiving intravitreal aflibercept and was intended to generate substantial cost savings while maintaining comparable treatment quality. This hospital-level conversion demonstrates how centralized procurement and structured switching programs can rapidly expand aflibercept biosimilar uptake among existing patients.

MARKET RESTRAINTS

Complex Patent Settlements and Launch-timing Uncertainty to Restrain Market Growth

Patent disputes and settlement-related launch restrictions are expected to limit the timely commercialization of ophthalmology biosimilars. Even after receiving regulatory approval, aflibercept biosimilars may remain unavailable due to preliminary injunctions, ongoing appeals, licensing negotiations, and patents covering formulations or other product characteristics. Settlement agreements can assign different market-entry dates to individual manufacturers, resulting in staggered launches and uncertainty for production, inventory, pricing, and procurement planning. These delays postpone revenue generation for biosimilar manufacturers and restrict competition that could otherwise reduce anti-VEGF treatment costs. Consequently, actual market growth may remain slower than indicated by the number of approved biosimilars.

• In September 2025, Sandoz settled its Eylea patent litigation with Regeneron. Still, the agreement permitted the launch of its FDA-approved aflibercept biosimilar, Enzeevu, only in the fourth quarter of 2026 or earlier under certain circumstances. Enzeevu had received FDA approval in August 2024, indicating a potential delay of more than two years between regulatory approval and commercial launch. The article also noted that Regeneron had alleged infringement of 46 Eylea patents, some of which extend to 2040, highlighting how extensive patent portfolios can create prolonged uncertainty for biosimilar market entry.

MARKET OPPORTUNITIES

Expansion of Affordable Biosimilars Across Asia Pacific to Create Significant Growth Opportunities

Asia Pacific offers considerable growth opportunities due to the increasing burden of diabetes-related retinal disorders, ageing populations, and continued gaps in access to advanced ophthalmic biologics. Expanding the availability of locally manufactured ranibizumab and aflibercept biosimilars in Southeast Asia can reduce dependence on expensive imported biologics and make repeated anti-VEGF treatment more accessible. Government initiatives to strengthen diabetic retinopathy treatment, combined with improving retinal-care infrastructure, are expected to enlarge the addressable patient population. Consequently, regional manufacturers can capture new opportunities through domestic launches, hospital partnerships, competitive pricing, and expansion into other underserved Asia Pacific markets.

• In February 2026, Zydus Lifesciences launched ANYRA in India, the country’s first indigenously developed aflibercept 2 mg biosimilar. The product is indicated for multiple retinal disorders, including wet age-related macular degeneration, diabetic macular edema, diabetic retinopathy, retinal vein occlusion, and myopic choroidal neovascularization. The launch demonstrates how biosimilar drug development, and commercialization can broaden biosimilar treatment availability in a major Asia Pacific market.

MARKET CHALLENGES

Strong Competition from Low-cost Off-label Bevacizumab to Challenge Commercial Uptake

The widespread use of off-label bevacizumab presents a major commercialization challenge for such biosimilars. The drug has been used for retinal diseases for several years. It is supported by extensive physician experience, established compounding networks, and substantially lower per-injection costs than licensed anti-VEGF therapies. Even when ranibizumab and aflibercept biosimilars are priced below their reference products, they may struggle to compete with the cost advantage of compounded bevacizumab. Hospitals, payers, and public healthcare systems may therefore continue to recommend bevacizumab as an initial therapy, particularly through step-therapy and cost-containment policies. This can restrict the addressable patient population, slow biosimilar conversion, and increase pricing pressure on ophthalmology biosimilar manufacturers.

• In May 2025, Retinal Physician reported that 54% of fee-for-service Medicare patients with neovascular age-related macular degeneration began treatment with low-cost compounded bevacizumab, compared with 41% who started with aflibercept. In a separate Medicare Advantage cohort, 70% of patients began treatment with bevacizumab. These findings highlight how the strong cost advantage and established first-line use of bevacizumab can limit the initial uptake and commercial potential of licensed ophthalmology biosimilars.

Segmentation Analysis

By Drug Class

Established Clinical Use and Earlier Regulatory Approvals Supported the Dominance of Anti-VEGF Antibodies Segment

Based on the drug class, the market is categorized into anti-VEGF antibodies, VEGF fusion proteins, TNF-α Inhibitors, and others.

The anti-VEGF antibodies segment dominated the market in 2025.

By Age Group

High Prevalence of Age-related and Diabetic Retinal Diseases Supported the Dominance of Adults Segment

Based on the age group, the market is segmented into pediatric and adults.

The adults segment dominated the ophthalmology biosimilars market share in 2025 as the principal diseases addressed by such biosimilars largely affect the adult and elderly populations. Wet AMD is strongly associated with aging, while diabetic macular edema and diabetic retinopathy develop mainly among adults living with long-term diabetes. Retinal vein occlusion and myopic choroidal neovascularization also account for greater treatment demand among adults than children. The larger eligible population and greater need for repeated anti-VEGF treatment therefore resulted in considerably higher product utilization among adults.

• In November 2025, Sandoz launched Afqlir, its aflibercept biosimilar, in Europe for the same adult retinal-disease indications as the reference medicine. The approved indications included wet AMD, diabetic macular edema, retinal vein occlusion, and myopic choroidal neovascularization, demonstrating the broad commercial focus on adult patients.

The pediatric segment is projected to grow at a CAGR of 16.79% over the forecast period.

By Route of Administration

Direct Drug Delivery to the Retina Established Intravitreal Administration as the Leading Route

Based on the route of administration, the market is segmented into intravitreal, subcutaneous, and others.

The intravitreal segment dominated in 2025, as the major ophthalmology biosimilars are designed to be administered directly into the vitreous cavity of the eye. This route delivers the biologic close to the affected retinal tissue, enabling adequate local drug exposure while limiting unnecessary systemic distribution. The repeated dosing requirements further increase the number of intravitreal procedures performed annually.

• In August 2024, Sandoz AG received the U.S. FDA approval for Enzeevu as a 2 mg vial kit and prefilled syringe specifically for intravitreal injection. The approval demonstrates that leading biosimilar manufacturers continue to develop their retinal products around the intravitreal route and related clinical workflow.

The others segment is projected to grow at a CAGR of 16.23% during the forecast period.
