The groundbreaking 操作／手術 brought 重要な 改良s in 見通し within a 事柄 of weeks.

The 手続き uses a person's own 独房s to 傷をいやす／和解させる 損失 to the cornea - the transparent outermost 層 of the 注目する，もくろむ .

It is carried out under 地元の anaesthetic, with 患者s returning home within two hours of 外科, 除去するing the need for expensive hospital stays.

The three 患者s 扱う／治療するd so far had very poor 見通し 原因（となる）d by corneal 病気 - the fourth most ありふれた form of blindness, 影響する／感情ing around 10million 世界的な.?

How it 作品: The 治療 can 回復する 注目する，もくろむ sight using steam 独房s

It is 原因（となる）d by genetics, 外科, 燃やすs, 感染 or chemotherapy, and 治療s usually 含む 汚職，収賄s and 移植（する）s and 麻薬s such as steroids.

The team from the University of New South むちの跡s in Sydney harnessed the 力／強力にする of 茎・取り除く 独房s - 'master 独房s' with the ability to turn into other 独房 types.

They 除去するd small 見本s of 茎・取り除く 独房s from the 注目する，もくろむs of two men and a woman with corneal 病気 and grew them on a 接触する レンズ.

The 茎・取り除く 独房-coated 接触するd レンズs were then put into the 患者s' 注目する，もくろむs for around three weeks.

During that time, the 茎・取り除く 独房s moved off the レンズs and began to 傷をいやす／和解させる the 損失d corneas, the 定期刊行物 Transplantation 報告（する）／憶測s.

Using a person's own 独房s 除去するs any need for 寄贈者s and means the 移植（する） will not be 拒絶するd.

研究員 Dr Nick Di Girolamo said: 'The 手続き is 全く simple and cheap.

'Unlike other techniques, it 要求するs no foreign human or animal 製品s, only the 患者’s own serum, and is 完全に 非，不，無-invasive.

'There's no suturing, there is no major 操作／手術. You don’t need any fancy 器具／備品.'

The 接触する レンズs used in the 操作／手術 are already 広範囲にわたって used after 注目する，もくろむ 外科. ?

The 研究員s hope the technique can be adapted for other parts of the 注目する，もくろむ, such as the retina,? and even どこかよそで in the 団体／死体.

損失 to retinal 血 大型船s is behind a 範囲 of 条件s that can lead to loss of sight 含むing many 事例／患者s of age-関係のある macular degeneration, or AMD, the most ありふれた 原因（となる） of blindness in the 年輩の.

Dr Di Girolamo said: 'If we can do this 手続き in the 注目する，もくろむ, I don’t see why it wouldn’t work in other major 組織／臓器s such as the 肌, which behaves in a very 類似の way to the cornea.'

Dr Kuldip Sidhu, a 茎・取り除く 独房 専門家 at the same university, said the 'clever 戦略' was a step に向かって using 茎・取り除く 独房s to 扱う／治療する debilitating human 病気s.

Professor 貸付金 Skene, of the University of Melbourne, said: '供給するd that 患者s are told that the new 手続き is 実験の and possible 危険s are not yet known, and they then 同意 to have it, this use of a 患者's 茎・取り除く 独房s is no more ethically contentious than a 肌 移植（する）.'

In Britain, Sonal Rughani, of the RNIB, said: 'This small-規模 熟考する／考慮する 明らかにする／漏らすs 約束ing 結果s with the use of 接触する レンズs. We を待つ その上の 開発s of this innovative nature.'

The work is one of several 熟考する／考慮するs 存在 carried out around the world which 目的（とする） to use 茎・取り除く 独房s to cure blindness.
