چکیده

هدف:
این مقاله، تعریف و اندازه­ گیری زاویه تماس خیسی، رطوبت پذیری لنز تماسی، تأثیر لایه اشک و محلول های لنز تماسی بر زاویه خیسی را مرور می ­نماید. همچنین، عملکرد بالینی این پارامترها نیز مورد بحث قرار خواهند گرفت.
روش بررسی:
در این مقاله مروری، مقالات منتشر شده در زمینه زاویه خیسی و رطوبت پذیری لنزهای تماسی، با استفاده از پایگاه های اطلاعاتی PubMed مورد بررسی قرار گرفت. بر اساس معیارهای ورود و خروج (مقالات بین سال های 1975 تا 2017، ارتباط با عنوان و موضوع بحث، رفرنس اصلی، عدم تکراری بودن، عدم تشابه موضوعی)، 66 مقاله با دقت، تحت مطالعه قرار گرفتند.
نتیجه­ گیری:
پارامترهای مختلفی از لنز تماسی در راحتی بیمار با لنز تاثیر دارند که این پارامترها شامل عبوردهی اکسیژن، ماده لنز، طرح لبه لنز، سختی لنز، ضخامت لنز و روشهای بهبود سطح می باشند. چنانچه تمام این فاکتورها را کنترل و ثابت در نظر بگیریم و تنها متغیر رطوبت پذیری باشد، رطوبت پذیری بهتر می تواند پارامتر مهمی در راحتی بیمار باشد. روابط بین زاویه خیسی، رطوبت ­پذیری و راحتی به دلیل وجود فاکتورهای متعدد، جای بحث دارد بطوری که این موضوع نیاز به تحقیقات بیشتر، در این زمینه دارد.
