This often means the edge of the ablation zone is within the visual axis, producing ghosting , starbursts , and/or halos .

یک سلول گیرنده نور ( photo receptor ) نوع خاصی از سلول موجود در شبکیه است که قادر به انتقال نور فضا است. اهمیت بیولوژیکی فتوریسپتورها این است که آنها نور (تابش الکترومغناطیس قابل مشاهده) را به سیگنالهایی تبدیل میکنند که میتوانند فرایندهای بیولوژیکی را تحریک کنند .برای مشخص شدن بیشتر، پروتئینهای فتوریسپتور در سلول، فوتونها را جذب کرده و موجب تغییر در پتانسیل غشاء سلولی میشوند. انواع گيرنده هاي نوري سلولهاي مخروطي به طور كلي نقش مهمتري در انجام وظايف
