Introduction: We report a case of a man with cataract and anterior megalophthalmos (AM), in which some myopia was retained when calculating intraocular lens (IOL) power using the Haigis formula to avoid postoperative farsightedness.
Case Description: A 59-year-old Chinese man was referred to our clinic for cataract surgery in his right eye. He had strong bilateral megalocornea, and his left eye had undergone surgery four times. After complete preoperative examinations and repeated biometry, the Haigis formula was used, and a 3-piece IOL was implanted with a target power of -1.97 D. At 1-year follow-up, the patient showed the best-corrected distance vision of 20/20 with the refraction of -1.50 DC × 160°, and the IOL was stable.
Conclusion: Our patient with anterior megalophthalmos showed postoperative hyperopia drift even though the Haigis formula was used as suggested in previous studies. To prevent farsightedness after surgery, some myopia should be retained when calculating IOL power. The Kane, Holladay II with AL adjustment, and Barrett Universal II formulas may be more accurate for calculating IOL power in such patients.

A 56-year-old male patient sought medical attention due to a gradual decline in bilateral visual acuity, which had been ongoing for a year and had rapidly worsened over the past three months. He received an initial diagnosis of bilateral concurrent cataracts and bilateral anterior megalophthalmos. Subsequently, cataract removal surgery was performed.

Objective: The aim of this study was to examine the biometric ocular manifestations and structural ocular features of anterior megalophthalmos (AM).
Methods: Fifteen patients with AM (30 eyes) from the Eye & ENT Hospital of Fudan University were included. The age-matched control group consisted of 30 participants (30 eyes) who underwent Pentacam HR and IOLMaster 700 measurements for one normal eye.

Anterior megalophthalmos is a rare, bilateral, nonprogressive, hereditary, congenital disorder characterized by the enlargement of all anterior segment structures of the eye, with megalocornea, iris atrophy, and zonular abnormalities. We report a case of an 8-year-old male who presented to the emergency department with a history of visual loss after a blunt ocular trauma to the left eye. The patient presented with markedly enlarged corneas and deepened anterior chambers bilaterally.
