About this study

The study aims to determine which technique, lathe cutting or cast molding, produces soft contact lenses that are more biocompatible and less likely to cause adverse effects on the eye. The findings from our research could have significant implications for contact lens wearers and manufacturers, guiding the production of lenses that promote better ocular health and enhance wearer comfort. Ultimately, this research contributes valuable knowledge to optometry and ocular surface disease management.

  • Patients with abysmal compliance.

Treatment and study plan

Soft contact lens with lathe cut technique Lathe

Other

athe cut technique Lathe cutting involves shaping a solid block of lens material into the desired form using precision machinery. This method allows for customized lens designs but may result in a less smooth surface compared to cast molding. Cast molding, on the other hand, uses a liquid monomer that is cured in a mold to form the lens. This technique typically results in a smoother and more uniform lens surface.

Soft contact lens with cast molding technique

Diagnostic Test

Participants in this arm would receive Cast molding soft contact lenses and would wear them according to the study protocol, also likely for a specified duration.The cast molding technique for soft contact lenses involves creating lenses by polymerizing a liquid monomer mixture within a mold that forms the desired lens shape. Here's a brief overview of the steps involved in the cast molding process

Primary outcomes

  1. Corneal epithelial integrity

    Time frame: 12 Months

    This involves assessing the health and integrity of the outermost layer of the cornea, which can be done through optical coherence tomography (OCT)

  2. Ocular surface symptoms

    Time frame: 12 months

    Utilizing standardized questionnaires or scales to assess symptoms such as dryness, discomfort, or irritation experienced by the subjects wearing the different types of soft contact lenses.
