Abstrakt: Objective: To evaluate short-term visual outcome, patient acceptance, and tolerance of mini-scleral contact lenses (SCLs) in the management of various corneal pathologies.
Design: Retrospective case series.
Participants: Thirty-two patients (40 eyes) who received mini-SCLs.
Methods: Single-centre retrospective case series, between February 2010 and January 2013, of 32 patients (40 eyes) with various corneal pathologies who were offered either Maxim 5R, Maxim 7, or Maxim 7 × 11 mini-SCLs for nonsurgical optimization of visual correction. Patients were followed up at 1 and 3 months for assessment of best-corrected visual acuity, comfort, length of daily wear, and complications.
Results: Thirty-two patients (40 eyes), with a mean age of 41 ± 16 years, opted to receive mini-SCLs. Eighteen patients had previously undergone surgery such as penetrating keratoplasty, deep anterior lamellar keratoplasty, and intraocular lens implantation. The median best-corrected visual acuity improved from 0.3 logMAR (range 0-1.3) before mini-SCLs, to 0.05 logMAR (range 0-1) with mini-SCLs (p < 0.0001). At 1-month follow-up, the median length of wear was 10 hours/day (range 1.5-15). At 3-month follow-up, the median length of wear was 12 hours/day (range 2-15). All eyes were comfortable at initial use of mini-SCLs and 91% were comfortable at 3-month follow-up.
Conclusion: Mini-SCLs may be a comfortable management option for patients with keratoconus and other corneal pathologies who are unable to achieve adequate visual outcome with traditional spectacles or rigid gas-permeable contact lenses.
