免擔心~不需近視雷射的度數,也可以精準進行白內障手術!!

免擔心~不需近視雷射的度數,也可以精準進行白內障手術!!
<本院擁有頂級Haag Streit-LENSTAR LS900水晶體測量儀>

近來『已接受近視雷射手術』的白內障患者大幅增加,而已接受近視雷射手術患者的角膜弧度較難測量及估計,過去時有所聞因患者記錯之前的近視度數,導致白內障手術中,水晶體計算錯誤,而需要將植入的人工水晶體取出,再植入正確的人工水晶體。為此本院在201511月斥資新台幣一百多萬元,購進可藉由高階雷射光學測量技術,提升手術前水晶體計算精準度的HaagStreit Lenstar LS900光學式人工水晶體測量儀。
 

利用非接觸式頂級HaagStreit Lenstar LS900光學式人工水晶體測量儀及同步APS自動定位系統,輕鬆精準地完成白內障手術前檢查
除此之外,利用非接觸式光學長度測量儀,可測得真正視軸並一次測量可得8種運算模式數據,即便是遇到近視雷射手術前近視、散光度數過深的患者,雷射後角膜弧度過平、高度近視眼軸過長或遠視眼軸較短的患者,都可選擇最適宜的測量公式及數據,降低誤差值,讓白內障手術前的人工水晶體計算這最關鍵的步驟,得到最準確的結果。而同步APS自動定位系統,更是讓每一次測量的視軸中心數據加倍精準。



本院斥資新台幣一百多萬元,購進頂級檢測機種~讓『已接受過近視雷射手術』的白內障患者不需憂心因水晶體計算錯誤而造成術後視力的不完美

白內障再見 失智症再見 Bye Bye Cataract.... Bye Bye Dementia

白內障再見 失智症再見 ...........(手術影片6:10)
Bye Bye Cataract.... Bye Bye Dementia

(手術影片6:10)

病人何是約90歲的病人,之前來到門診檢查時行動相當遲緩,需要家屬一直攙扶著、且病人總是悶悶不樂、不發一語,原來是因為發生白內障自覺視力越來越模糊­致憂鬱症(Depression)及失智症(Dementia)現象日益加重

據家屬透露~甚至有幾次自殘行為想了結此生。因兩眼均屬過熟型白­內障hypermature cataract,視力伸手不見五指hand movement 10cm.,幾乎全盲,以至於他毫無求生意志

於上個月做完左眼手術,病人隔天手術後回診,視力就進步到0.4,家屬及病人皆相當開­,手術後回診的第一天,病人神情明顯變得愉快,而且和主動和我們­診所醫護人員打招呼,與尚未手術時的樣子實有天壤之別。

因為患白內障而看不清楚產生憂鬱症狀的患者,診所並不是第一次遇到,之前我們也手術過幾­個類似的案例,等白內障手術開完
視力變好之後,患者情緒皆有顯著改善,這樣的復原結果同時也總是鼓舞了我們每個參與手術的同仁

1.Cataract Removal and Alzheimer's Disease

The removal of cataracts can improve vision and reduce accidents and falls. However, some individuals, caregivers, and primary care doctors are reluctant to proceed with cataract surgery once an individual is diagnosed with Alzheimer's disease because they think that cataract surgery will not improve the person's quality of life, vision, and cognition. The investigators have designed this study to determine whether or not this belief is true......................................................

2.Alzheimer Research: Cataract Surgery for People with Dementia Improves Vision and Quality of Life
Results from a new clinical trial, presented at the July 2014 Alzheimer's Association International Conference, suggest that cataract surgery may slow mental decline in people with Alzheimer's disease and related dementias. Preliminary study results indicate that improved vision, resulting from cataract surgery, can have a variety of benefits – both visual and non-visual – for people with dementia...............................
