Pitting stain with soft contact lenses--Hydrocurve thin series

Area of Science:

• Ophthalmology
• Corneal Health
• Contact Lens Technology

Background:

• Hydrophilic contact lenses are widely used.
• Steep-based curve designs are common in certain lens series.
• Corneal staining is a potential complication of contact lens wear.

Purpose of the Study:

• To investigate the incidence and characteristics of corneal staining in patients wearing Hydrocurve thin series hydrophilic lenses.
• To identify and describe a specific pattern of corneal epithelial staining associated with these lenses.

Main Methods:

• A survey was conducted on 85 patients (170 eyes).
• Patients were wearing relatively steep-based curved Hydrocurve thin series hydrophilic lenses.
• Corneal staining was assessed and categorized by severity (light, moderate, heavy).

Main Results:

• 32% of the eyes examined showed corneal staining.
• The identified staining pattern was designated as "Pitting Stain."
• Pitting Stain presented as concentrated, superficial, punctate staining, with potential for coalescence and deepening into branching patterns.

Conclusions:

• A significant percentage of patients wearing specific Hydrocurve hydrophilic lenses experienced "Pitting Stain."
• This type of corneal staining is characterized by its unique appearance and potential progression.
• Further research may be warranted to understand the etiology and management of Pitting Stain in contact lens wearers.
