Purpose

To measure and analyze corneal astigmatism in 1000 consecutive cataract surgeries in a hospital in Barcelona

Setting

Germanes Hospitalàries del Sagrat Cor de Jesus “Hospital Sant Rafael”, Barcelona

Methods

Refractive and keratometric data of 1000 eyes of 624 patients operated consecutively in the last 6 months for cataracts were retrospectively analyzed -after excluding all those cases with corneal pathology that could alter the baseline values, and also those whose data could be less reliable-.

A descriptive statistical analysis was carried out in order to determine the type, degree and distribution of corneal astigmatism in these patients.

Results

Mean age of the 624 patients was 76.5 ± 7.3 years (range 45 to 98), with more women than men (61.38%).

Mean keratometric value and corneal astigmatism was 44 ± 1.55 D (38.875 to 48.25) and 0.91 ± 0.61 D (0 to 4.5) respectively.

Corneal astigmatism was less than 0.5 D in 14.59% of eyes, but greater than 1 D in 41.97% of the cases (> 2 D in 7.95% and >3 D in 1.28, with no cases greater than 4.5 in our sample). Corneal astigmatism was with the rule (WTR) in 27.83% of cases and against the rule (ATR) in 54.03% (oblique in 18.14%), observing a change with age from WTR to ATR.

Conclusion

Mean corneal astigmatism of our sample was 0.91 ± 0.61 D, being in 27.83% of the cases WTR, 54.03 ATR and 18.14 oblique; these results are very similar to those reported in other studies in populations very different from ours, but a bit different in respect to others with similar population.

There is also a coincidence in the observation that there is a change in the axis of astigmatism from WTR to ATR with the age.

Cataract surgery is one of the most widespread surgical techniques in the world, becoming practically a refractive surgery in recent years. In this order, treatment of astigmatism in these patients is a key point to obtain satisfactory results, and so it is mandatory to know the population that we are going to treat; in our case, 41.7 % of the patients had more than 1 D of corneal astigmatism.

These data can therefore be of interest for both the industry and health providers.
