China’s Progress in Complex Eye Surgery
What international patients should know about corneal disease, retinal repair, glaucoma and specialist assessment.
Published · Evidence and sources checked 30 September 2026
What the evidence shows
China's ophthalmology capability can be evaluated through published surgical research, specialist-center experience and regulatory decisions. These sources offer reasons to consider a specialist opinion, particularly when a diagnosis or previous treatment leaves difficult questions. They do not establish one success rate for every complex eye condition. Improving vision, stabilizing disease, retaining an implant and avoiding complications are different outcomes.
This guide focuses on the evidence behind selected services and the practical questions to resolve before considering care abroad.
Urgent eye symptoms should not wait for travel. Sudden vision changes, new flashes or a sudden increase in floaters require prompt local assessment; suspected retinal detachment should not wait for international coordination. [13]
What is changing in China
A September 2026 report hosted by China's National Health Commission describes a 2026–2030 plan to expand eye-care access and strengthen services. This is policy direction, not evidence that every hospital already has the same specialist resources. [1]
Published experience provides more concrete context. A survey of 64 Chinese hospitals recorded 36,616 corneal transplant operations during 2014–2018. These historical participating-hospital figures demonstrate an established field; they are not today's nationwide annual volume. [2] Glaucoma research also documents changing surgical practice across institutions. Selecting the right subspecialty team matters more than treating national scale as a guarantee. [7]
Corneal disease and transplantation
Corneal transplantation may be considered when damage to the transparent front of the eye limits vision. The operation and its follow-up depend on the affected tissue and the underlying disease. A previous failed graft requires a different discussion from a first transplant in an otherwise healthier eye. Rejection, infection and graft failure are relevant concerns, and prescribed drops and follow-up remain important long after discharge. [11]
The Chinese survey included centers such as Shandong Eye Institute, Zhongshan Ophthalmic Centre, Beijing Tongren Hospital and Fudan's Eye and ENT Hospital. Their inclusion establishes participation in published clinical work, not a MedVoyage partnership or a current promise to accept an overseas patient. [2]
Before committing to travel, ask the institution to confirm the proposed procedure, donor-tissue availability where needed, expected monitoring and how care would continue at home. A hospital-specific assessment is necessary before discussing dates or prices.
Artificial cornea: specialized innovation with substantial follow-up
A 2021 regulatory announcement reported approval of an artificial cornea manufactured by Beijing Mihe Medical Instrument. Approval concerns a particular device; it does not make artificial cornea a routine substitute for every transplant. [3]
A 2026 single-center, single-arm study examined Mihe implantation with ear-cartilage reinforcement in selected patients with bilateral end-stage corneal blindness. Of 36 enrolled patients, 35 completed implantation; 34 retained their initial prosthesis at the final visit. Average follow-up was 68.84 months. Reported complications included infectious endophthalmitis in 3/35 eyes (8.57%) and newly acquired glaucoma in 3/35 (8.57%). These events may overlap. Implant retention is not equivalent to normal vision or freedom from complications. [4]
This study supports a focused discussion about a specialized option, with its risks presented alongside its potential benefits. It cannot establish comparative superiority or predict the result for an individual patient.
Keratoconus and corneal cross-linking
For progressive keratoconus, the treatment discussion should distinguish disease stability from better vision. A prospective Fudan study published in 2023 followed 44 eyes of 40 patients after accelerated transepithelial cross-linking. Corneal curvature and thickness measurements remained stable over five years; the authors reported no postoperative complications. Visual acuity did not change significantly from baseline. [5]
This small study provides evidence about one protocol in selected patients. It does not establish that every cross-linking method is equivalent, that no patient experiences complications, or that normal vision will return. Ask the corneal specialist what progression has been documented, which protocol is proposed and what visual correction may still be needed.
Retinal surgery: repair and vision are separate outcomes
A Chinese multicenter retrospective series published in 2017 reported on 159 patients treated during 2007–2012 with a combined approach for selected complicated rhegmatogenous retinal detachments. At an average follow-up of 13.76 months, primary anatomical success was 146/159 eyes (91.82%); final reattachment after salvage management reached 98.11%. However, 62/159 eyes (38.99%) achieved best-corrected vision of at least 20/40. [6]
These historical findings illustrate why retinal attachment and useful vision should be discussed separately. They do not describe every retinal detachment or establish present-day nationwide performance. Patients considering vitrectomy or other retinal procedures should ask which outcome is realistic for their diagnosis and whether further operations may be necessary.
Retinal detachment is an emergency. A travel plan should never replace timely local care for new symptoms. [13]
Glaucoma and complex cataract planning
Chinese research covering 57 hospitals in 30 provincial regions documented shifts in glaucoma procedures during January 2015–September 2019, including increased combined cataract–glaucoma surgery. [7] A more recent single-center report, published in 2025, described 13,092 glaucoma operations at Fudan's Eye and ENT Hospital during 2013–2023. These studies show clinical experience and changes in practice, rather than proving a particular procedure is best for everyone. [8]
Glaucoma treatment aims to prevent additional damage; it does not reverse established vision loss. Eye-pressure monitoring and ongoing treatment may still be needed after surgery. [10]
A cataract clouds the eye's lens, but someone with several eye conditions needs an assessment of the whole eye. [14] If cataract and glaucoma coexist, ask whether procedures should be combined or staged and what improvement is realistically expected. A more expensive lens or a newer surgical label should not substitute for an explanation of suitability.
Diagnostic support and AI
In February 2025, China's NMPA announced approval of software supporting diagnosis of several fundus diseases from eye images. This is a concrete diagnostic-development example. It is an aid for doctors, not a replacement for an ophthalmologist, and its approval does not establish surgical outcomes. [9]
For a second opinion, ask which existing scans and reports can be reviewed and which examinations need repeating in person. The aim is a clear diagnosis and treatment question, rather than collecting the largest number of tests.
How to interpret the numbers
| Evidence example | What it tells patients | What it does not establish |
|---|---|---|
| Corneal transplant survey [2] | Experience across participating hospitals | Current national volume or individual graft survival |
| Artificial-cornea study [4] | Implant retention and recorded complications in selected cases | Normal vision, zero risk or superiority |
| Cross-linking study [5] | Five-year observations for one treatment protocol | Guaranteed visual improvement |
| Retinal series [6] | Anatomical repair and visual acuity can differ | One success rate for all retinal surgery |
| Glaucoma practice studies [7][8] | Available experience and evolving procedure selection | Reversal of existing optic-nerve damage |
Ask for results in patients with a similar diagnosis, using the same procedure and a clearly stated follow-up period. A percentage without its denominator, outcome definition and observation period is insufficient for a decision.
Travel, follow-up and costs
If retinal surgery leaves a gas bubble inside the eye, do not fly or travel to high altitude until it has dissolved and the treating team has confirmed appropriate travel arrangements. A short hospital stay is not permission to fly. [12]
Arrange a named follow-up clinician, access to prescribed medicines, translated operation records and a clear route for urgent advice. Corneal graft monitoring and glaucoma care may continue long term. [10][11] Ask for an itemized estimate covering assessment, surgery, devices or tissue where applicable, medicines and follow-up. Confirm separately whether interpretation, accommodation and additional procedures are included. This guide does not provide a verified international-patient price or waiting-time promise.
How MedVoyage China can help
MedVoyage China can help organize non-clinical case information, coordinate questions and appointments, and clarify practical arrangements with institutions. Diagnosis, urgency, treatment selection and travel fitness remain decisions for qualified clinicians. Hospital acceptance and clinical outcomes cannot be guaranteed.
Start with your main question and the records already available. Confirm a private submission channel before sending detailed medical information. For urgent symptoms, seek local care rather than waiting for a coordination response.
Questions & answers
Can international patients seek complex eye care in China?
They can ask an appropriate institution to assess their records and needs. Current admission requirements, specialist availability and language support must be confirmed directly. A publication from a hospital is evidence of research participation, not confirmation that it can accept your case or offer a particular appointment date.
Does a corneal transplant require long-term follow-up?
Yes. Recovery and monitoring continue after discharge, and prescribed drops may be needed long term. Rejection can occur later, so arrange follow-up and know how to obtain urgent assessment if symptoms change. Confirm responsibilities between the operating center and your local ophthalmologist before traveling. [11]
Is an artificial cornea suitable after every failed graft?
No blanket eligibility can be inferred from the studies here. The cited Mihe study involved carefully selected patients with bilateral end-stage disease and used a particular reinforced technique. Its retention results must be considered together with recorded complications and specialist assessment of the individual eye. [4]
Does successful retinal repair mean normal vision?
Not necessarily. Anatomical reattachment and visual recovery are different measures. The cited Chinese series reported both, with different proportions reaching each outcome. Ask the surgeon what level of vision is realistically expected in your situation and whether additional treatment may be required. [6]
Can I fly home soon after eye surgery?
There is no universal return-flight schedule. In particular, an intraocular gas bubble prevents air travel until it has dissolved. The team must explain restrictions for your actual procedure and recovery. Avoid assuming that discharge or completion of the operation means you can safely board a flight. [12]
What should I prepare for an initial review?
Ask the receiving institution for its records checklist. Useful material may include the diagnosis, eye-operation history, current medications, vision measurements and existing imaging reports. State which eye is affected and your main concern. Use an agreed private channel and keep copies for the clinicians who will provide follow-up.
