Atomik kuvvet mikroskobisi (AFM) ve kuvvet spektroskopisi (FS) malzemenin mekanik özelliklerinin nanoölçekte belirlenmesini sağlayan bir yöntemdir. Bu çalışmada, birinci nesil kontak lens malzemesi olan metakrilat (MA) temelli kopolimerler kullanılarak üretilen lenslerin mekanik ve optik özelliklerinin geliştirilmesi amaçlanmıştır. Farklı içeriklerde ve farklı çapraz bağlanma oranlarında üretilen kontak lenslere in situ polimerizasyon süreci ile nanoparçacık ilave edilmiş ve mekanik testleri AFM kullanılarak gerçekleştirilerek elastik davranışları incelenmiştir. Nanoparçacık ilavesi ile değişen optik özellikler ise elipsometre kullanılarak karakterize edilmiştir. Düşük miktarlarda (kütlece %2’den az) nanoparçacık ilavesi ile elastik deformasyon özelliklerinde 2 kat kadar artış ve özellikle UV bölgede ışık soğurum oranında artış elde edilmiştir. MA neslinden olan (1. Nesil) lenslerin, üretim yönteminde büyük değişiklikler yapılmaksızın daha yüksek dayanım ve olumlu optik özellikler içerecek şekilde üretilmesinin mümkün olduğu kanıtlanmıştır.
