Lasik vs ICL: my review

This post is mainly for the people who are researching on vision correction options. Ive read up so much (blogs/reviews on lasik) and been to some forums. So here is my chance to give back to my community (the short-sighted community) Lol... Here we go!

Disclaimer: this is all I know but is not gonna be 100% correct due to doctors/optometrists/bloggers subjective opinions... And perhaps my own memory slips! Do more research if you want to do any vision correction surgery!

Firstly, my background:
I'm the girl who's been wearing glasses since I was 9. I've always set my eyes on lasik since that's what my dad did... Until I found out about Implantable Contact Lens (ICL). 

And I was faced with a huge decision to make, as each option has their pros and cons.

Here is what I gathered from my own research and visits to the doctor, with regards to comparison between ICL and Lasik.

Visual clarity 
Research says that ICL gives better visual quality than lasik for high refractive errors above 600 degrees (which mine is obviously super high la haha). 
Link: http://www.ncbi.nlm.nih.gov/m/pubmed/22865405/

People can have 6/6 (perfect) vision with bad visual quality - you can see up to the last line in the eye check, but it's just not completely sharp. 

Also, ICL has fewer instances of glares, haloes and dry eyes, which are common side effects of Lasik. 

BUT
So far, I've been to 3 lasik/ICL centers, and something seems quite weird... The mainly-ICL center said that ICL would definitely give highest quality vision, however, the mainly-lasik center says that their technology gives comparable vision quality.... Shrugs... It's a 自卖自夸 (praise whatever you sell) thing, but really scary because it's something I have to live with for the rest of my life!!

Iridotomy
I've read online about many complaints of iridotomy procedure in ICL (for the layman, it's something like the ICL will block the flow of liquid in the eye, so the doctor has to "poke holes" in the eye).

From the reviews I've read, the iridotomy is really horrible because of the increased glares and also it hurts!! If you're interested in ICL, you probably read the horror stories with regards to iridotomy too, but that's for the lower technology ICL lens. The newest 4th generation lenses has holes in them, making iridotomy obsolete, so you don't have to worry! (Not sure if these lenses are available in every country yet, from what I read there will be some FDA approval waiting time)

Risks
Lasik has a 0.01% risk of Ectasia (cornea steepening, and in worst cases, require a corneal transplant!!) while ICL has 1% risk of glaucoma and cataracts. 

I was initially put off by Lasik because I am so afraid of getting Ectasia!! But doctor has informed me that my cornea is thicker than average and my chances of Ectasia are pretty low. 

For ICL, glaucoma and cataracts can be halted - refer to next point about maintenance.

Maintenance
Lasik is much more fuss free compared to ICL (after the 2 post-op surgery checks, there is no need for visits to the eye doctor anymore). Whereas for ICL I'd need to visit the eye doctor EVERY year!! 

The doctor explained that she needed to monitor if the lens is still in place--- too big it'd cause glaucoma and too small it'd cause cataracts when it scratches on the natural lens! OTL 

Btw, you'll only realize you have glaucoma when it's very serious- there are no symptoms. Also, it causes vision loss which is irreversible due to permanent damage of optic nerves. 

Eye condition when the eye ages- cataracts
I won't deny that I was shocked when doctor told me that everyone will eventually have cataracts. To treat cataracts, the ICL must be removed and a new lens is put in!! Throwing away something so pricey is really... Ahh so wasted! (Not to mention that people with high myopia have higher risk of cataracts) (Mehh!!! High myopia is NOT FUN!)

Furthermore, there're some risks of removing the ICL (it's an invasive procedure). Whereas in the case of lasik, the procedure for cataracts follow the general treatment procedure (like for someone who didn't go vision correction surgery).

Weighing ICL and Lasik
ICL- better visual outcome, however, must live with yearly checks, and finally a removal when cataracts come along.

Lasik- not-so-optimal visual outcome (??), but lower maintenance.

Conclusion
Yup, that's all the info I have! What decision will I make? Stay tuned!!!

[FW] 高雄。黎明眼鏡。驗配硬式隱形眼鏡心得+十年經驗分享

話說將將配戴硬式隱形眼鏡默默地也十年了 最近身邊剛好有兩位朋友第一次配戴硬式隱形眼鏡 詢問我一些經驗和心得 加上我的硬式隱形眼鏡又意外地掉了!!!(杯具) 想說配戴這十年來,心得和繳的學費也算不少 上來分享一下~ 配戴硬式重要的是評估弧度和直徑的技術,過程很繁瑣, 所以如果去一般連鎖眼鏡行,大部分都會勸退 「現在比較流行軟式,很少人在戴硬式啦」(鄙視的口氣) 「硬式戴起來很不舒服喔!!」(威脅的口氣) 「硬式很危險,你想想一片玻璃在你眼睛裡破掉的樣子!!」(驚恐的口氣) 以上都是聽朋友說的真實案例 強烈建議去專門驗配硬式隱形眼鏡的店家或診所驗配 將將配戴硬式隱形眼鏡大概換過三副, 第一次配是在十年前,完全沒有做功課, 覺得有醫生加持的眼鏡行應該比較值得信賴, 就選擇了新莊藍主任眼科裡的附設眼鏡部, 因為歷史久遠已經不太記得配戴的過程, 只記得問了很多問題(像是洗眼鏡要滴幾滴水),問到驗光師有點不耐煩(我的錯)。 中間掉了兩次,因為有了硬式隱形眼鏡後, 將將就沒重配過一般眼鏡了,沒有一般眼鏡可以暫時替用, 所以直接請眼鏡行依舊的度數資料重做。 第三副重配時,貌似我前兩次掉都是掉同一眼, 以致於我另一眼已經使用了五年多,鏡片已經變形, 造成我的角膜也跟著變形,之前的弧度已經不適用了。 所以說硬式鏡片還是有壽命,過了兩年還是送回原廠檢查一下 照理說,要驗配硬式應該要讓眼睛休息一個禮拜沒戴硬式, 若有戴軟式也要休息一天, 不過因為我沒有一般眼鏡可以使用, 高度近視外加散光,買個臨時的軟式也很貴, 所以就硬要驗光師幫我配, 結果當然是不盡理想。 只記得眼球的弧度怎麼戴都不甚清楚,一直送回去工廠修都修不好, 後來就懶得追究了,降默默地也戴了四年(壞榜樣不要學我) 這次重配,開始懂得做功課,找了ptt上好評不少的 黎明眼鏡行 地址:高雄市鳳山區中山東路64號1樓 電話:07-747-4287 (要驗配硬式隱形眼鏡因過程約2小時,務必預約) 新裝潢,內部很乾淨舒適 本想拍個過程照片來分享,不過黎明眼鏡行表示是商業機密,不太方便.... 只好用口述的:...
