An algorithm for computing astigmatic refractive errors from ocular parameters.

Abstract

Calculation of total refractive astigmatism by analyzing refractive parameters of the individual components can be very tedious, especially when the principal meridians among all the components are not orthogonal. A straightforward programming algorithm for accomplishing these calculations is presented. The algorithm is applicable to any programmable device which performs trigonometric functions.

Implantation of foldable intraocular lenses in the presence of anterior capsular tears.

A consecutive series of patients who had undergone small-incision phacoemulsification cataract surgery with foldable lens implantation were reviewed. Seven patients had sustained anterior capsular tears during surgery. In all cases a three-piece foldable intraocular lens (IOL) was successfully inserted by careful positioning of the haptics. In all 6 patients available for long-term assessment the IOL remained stable and well centred, the tears having been sealed by fibrous tissue. We show that, if logical measures are taken to limit tear extension, the lack of an intact capsulorhexis need not result in conversion to extracapsular cataract extraction.

How successful is corneal transplantation? A report from the Australian Corneal Graft Register.

Corneal graft outcome was assessed within a large, prospectively collected database of 4499 records. Penetrating corneal graft survival was 91% at 1 year, 72% at 5 years and 69% at 7 years. The three most common indications for graft were keratoconus (30%), bullous keratopathy (25%) and failed previous graft (18%); the three most common causes of graft failure were rejection (34%), infection (18%) and glaucoma (9%). The vast majority of grafts were performed for improved visual acuity. About four-fifths of recipients achieved at least one line of better acuity on the Snellen chart post-operatively; of the remainder with unchanged or worse acuity, only 21% had failed grafts. Overall, 43% of recipients achieved a best corrected Snellen acuity of 6/12 or better, 52% achieved 6/18 or better, and 20% had acuitities of less than 6/60. Reasons for poor post-operative acuity (recorded as less than 6/60) included graft failure (41%) and comorbidities in the grafted eye (43%). A number of risk factors for graft failure were examined: in most instances, there was little room for decision-making or expert intervention.
