Factors contributing to corneal decompensation with the Stableflex lens

Area of Science:

• Ophthalmology
• Biomedical Engineering

Background:

• Small-diameter, closed-loop anterior chamber lenses, such as the Stableflex intraocular lens, have been associated with corneal complications.
• The underlying reasons for these complications, particularly in relation to preoperative ocular biometry, require further investigation.

Purpose of the Study:

• To investigate the relationship between preoperative axial length measurements and the development of corneal problems in eyes with Stableflex intraocular lenses.
• To determine if axial length measurements can predict the need for lens removal or penetrating keratoplasty in these eyes.
• To assess the utility of axial length measurements in the preoperative sizing of anterior chamber intraocular lenses.

Main Methods:

• A retrospective review of 38 eyes with Stableflex intraocular lenses requiring lens removal or penetrating keratoplasty was performed.
• Preoperative axial length measurements from these eyes were compared to control eyes.

Main Results:

• Eyes with Stableflex intraocular lenses that developed corneal problems exhibited significantly lower preoperative axial length measurements compared to control eyes.
• This finding suggests a correlation between short axial length and adverse outcomes with these specific anterior chamber lenses.

Conclusions:

• Short axial length is identified as a potential risk factor for corneal complications associated with small-diameter, closed-loop anterior chamber lenses.
• Preoperative axial length measurement is recommended as a valuable tool for predicting complications and guiding the selection and sizing of anterior chamber intraocular lenses.
