Abstract Details

Purpose:

To evaluate visual response of the limbus to limbus astigmatism wearing standard corneal shaping lenses for orthokeratology (O-K).

Setting:

At the privat eye clinic.

Methods:

Case report of a 20-year male patient, present himself 7th January 2015, his vision was blurring, formerly his diagnosed keratoconus both eye.  It was performed both eye comprehensive eye examination; visual acuity, autorefraction, visual correction, corneal topography, keratometry, slit lamp anterior eye examination, intra ocular pressure (IOP) examination, and funduscopy. The follow up schedule:once a week, then once every two weeks, once for every month for 3 months, once every six month. At each visit, he was performed both eye comprehensive eye examinations.The lenses consist of four-curve design. The lenses have worn during sleep minimally 8 hours.

Results:

Visual acuity(VA)right eye(RE) was 6/50corrections S-2.00C-3.50 x180:6/7.5; left eye (LE)VA 6/9 correction S-1.50C-2.75x180:6/7.5,his RE autorefraction was S-2.50C-6.00 x174; LE autorefraction was C-6.00x180.Topography shows limbus to limbus astigmatism RE flat K was 8.2,k was 7.4.LE flat K was 8.2, k was 8.00.SlitLamp,funduscopy,IOPboth eye were normal.The patient was fitted with an O-K lenses,RE RF3.00 BC9.00,CT 0.21mm,power +0.50D,Diameter10.6mm,LE:RF3.00 BC 900,CT 0.21mm, Power +0.50D, diameter10.6mm.He wore trial lenses for 1hour.Then the lenses were off. The RE VA was 6/6; LE VA was 6/6. The next day follow up of Unaided Visual Acuity (UVA) RE was 6/6, UVA LE was 6/6 up to now.

Conclusions:

the limbus to limbus astigmatism in this patient can be treated using O-K lenses with UVA right eye and left eyes gained 6/6 for many years.
